For Weight Loss: "My Dr decided to start me on Phentermine (37.5mg) because I'm morbidly obese and do not want to go the surgery route. Today (7/9/18) I took my 1st pill at 1030am. From reading your reviews I hope this wasn't too late in the day, and won't keep me up tonight. I'm 5'5 weighing in at 280 pounds..I have a 20 day supply. That is not covered through my insurance. Hoping to lose 15 pounds in these first 20 days.. Wish me luck!!"

Adipex-P (phentermine) for Weight Loss: "I have always been 130 lbs, but since having my last child I went up to 171lb! I have tried losing weight but nothing was working then I started steadily gaining to my current 184lb (I am 5'4"). Doctor checked my thyroid and all is well. I asked my doc about this medication and if it was right for me. I will see him every 30 days, with a 3 month limit on this medication. I have been on this med for maybe 2 weeks and have not weighed myself yet, but I have definitely noticed a change in my appetite. I no longer want to snack at night, and I am not always hungry. The first day I felt slightly jittery, and my mouth was so dry. Now I no longer feel jittery, my mouth is dry for about 3 hours after taking. I don't feel like I have a ton of energy, but when I get home after working a medium paced 8 hour job I am really tired when I get home. I have been keeping a close eye on my food and water intake. I am curious if I have lost any weight."

For Weight Loss: "I just finished my 1st bottle of #30 37.5 mg pills yesterday, 7/6/2018. I am a 46 year old male I weighed 334 lbs the morning I started taking them and this morning I weigh 309 lbs (25 lbs lost). I started taking them because I was very athletic in my younger years and my knees are worn out I needed to lose weight before having a total knee replacement on both knees. I feel so much better that I am able to postpone the operation and I plan to lose at least 50 more lbs. If you start taking them do it on the weekend. The pills are a little intense at first, like drinking too much coffee. Makes you a little spacey too. Also keep track of your calories. I was eating too little and it was making the side effects worse. The side effects wear off after a week or two and you do start to get your appetite back but it's a lot easier to manage portion sizes. I get sinuses and a runny nose and this drug works better to clear that up than anything else I have ever taken. Really happy with this."

For Weight Loss: "I have been taking phentermine 37.5mg since March 18, 2018. As if today July 6, 2018 total weight loss is 53 lbs. My starting weight was 250, today 197. I have severe arthritis in hips knees and ankles so I can't do any workout programs. I have added in a strict 1200 calorie, high fiber, low fat, low carb, and low sodium diet. The only downside I am experiencing is severe constipation. I have to take at least 1 women's laxative a week. Other than that I am pleased with my results!"

For Obesity: "This is my 2nd time on Phentermine 37.5mg. Started taking it back last year on 8/20/2017. First day it worked wonders!! Decreased in appetite, burst in energy and of course dry mouth. First prescription it worked. Second prescription it was still working but the effects of wanting to eat more were creeping back. I lost a total of around 15 pounds in 1 month & 10 pounds in the 2nd month. SW: 186lb. Today I'm back on it again because I gained again. When I got on the scale this morning I weighed in @ 194.2lb. Took my first pill around 7 something this morning. It's about two hours later & I still feel the same nothing has changed. I'm eating pretzel peanut butter nuggets as I'm typing. I hope and pray this 2nd time it works just as it did last year. Maybe this time I have to wait a couple hours. Also, while taking my pill this morning I also took my multivitamin & probiotics gummies as well as my vitamin D gel pill. Not sure if this is the reasoning it's not taking effectiveness yet"

For Weight Loss: "68-year-old female. I have RA which makes it hard to exercise, thyroid issues, post-menopausal and I take prednisone. Almost impossible for me to lose weight. Started on phentermine 15mg six days ago and have lost 7 pounds--from 170lb to 163lb. Need to lose 16 more. Plan to eat about 800 calories/day with one day @1200. The first day I had a headache and only slept 3 hours that night. No side effects since then except sleepiness in afternoon. Curbs appetite but still get hungry. A little food satisfies me. I took Redux and it stopped working after one month. I plan to take this three weeks on, three weeks off if that happens."

Adipex-P (phentermine) for Weight Loss: "Hi everyone!! I am a 41 year old married mother of 4. I weighed in at 245 lbs at 5'7. For years, I have had bouts of depression and self loathing. Well, I have finally decided to do something about my weight and got the Phen shot Wed, June 27 and began taking the Adipex 37.5mg Thursday. I must tell you, I feel fabulous!! My energy is way up and mentally I feel really good almost like a feeling of euphoria. I have no appetite. I have to force myself to take a few bites. I would rarely drink water but now it is my best friend!! I have not drank anything but for 2 days now. I have dry mouth (and the tinge of stinky breath I read about in the reviews), but I can definitely deal with it. And I spend 30 minutes a day on the treadmill. Sorry to be so long, but I had to tell someone :) I really think I found something that's finally going to work for me!! I can't wait to be slim again, to be able to bend down and tie my shoes without giving out of breath!!"

For Weight Loss: "I’m starting tomorrow since it’s too late today. It’s 5:30pm here in Arkansas. My insurance doesn’t cover it so out of pocket is about $27, but I found a prescription card that lowers it to only $12.00. SW is 228. I’m 5’4 and 32 years old. My GW is 190."

For Weight Loss: "Hi, I have been taking Phentermine 37.5mg since March 24th. I wrote a brief review that day as a starting point. It has now been 3 months, the max time suggested because after that it stops working as your body has gotten used to it. I am very happy with the results! I started at 146 lbs and am now down to 124.5 lbs. This is a healthy weight for me. I found this prescription helpful in training my brain into making healthy choices. In my opinion, this medicine not only helps curb appetite but also blocks cravings. They say it takes 3 months this to change a habit, and I am hoping this is true! The only reason I gave it a 9 is due to the dry mouth. Although, it helped me drink more water! Keeping sugar free gum hand helps with that also. For someone just starting this medication, I would suggest half of a pill for the first 2 days due to jitteriness. The weight fell off quickly at first, then slowed to about 2-3lbs a week."

For Weight Loss: "I started taking my first dose of 30mg of phentermine today, my doctor put me on it for a weight loss aide. I started out weighing 204lb in the office at 5'4, I plan to hopefully get down below 160lb. I have a monthly weigh in next month in July and I can't wait to see what the scale says. But for the most part today I have felt a ton of energy and I have been super thirsty, to the point where I had three drinks in front of me earlier. Very excited to see where this drug takes me in part of starting the Paleo diet, will keep updated."

For Weight Loss: "I’m 5’9 1/2 and weigh 180.4 pounds down from a 190lb in April 2018 that was really hard because I have two sons, full time job, husband and house! I decided to put me on the schedule and started working out at 5 am ! I have now stopped losing weight and inches and my diet with the kids activities in the evening are horrible ( during the day at work AMAZING). So Wednesday June 20, 2018 I popped my first pill! Wish me luck"

Adipex-P (phentermine) for Weight Loss: "**Update I originally weighed 374 pounds, and I got all the way down to 304lb on my own by exercising. Unfortunately, my weight picked up and I hovered at 320lb for years. I became so tired and desperate, I called the doctor fearing weight gain. She put me on Adipex in March of 2017 and I lost weight down to 221. Then I was off Adipex for 4 months and only gained 10 lbs, bringing my current weight to 231 lbs. This drug helped me to use the tools of weight loss more effectively. You still have to eat healthy and exercise. It does help you focus better and not to constantly contemplate food. Hopefully, this round I can drop below 200!"

Adipex-P (phentermine) for Weight Loss: "I just started the Adipex on 6/12/18, I weighed 213lb the day I started. I followed the low calorie diet of 1200 calories per day, cut out sugar. No side effects except dry mouth, I hated water before this but now I have no choice. Today 6/14/18 went for follow up appointment I'm 209lb that's 4 pounds in two days no gym. I walk a little at work but nothing major. My husband was sceptical about this, but now he seen the proof in me and is scheduled next Tuesday the 19th, to see the doctor for his prescription. I'm so excited for him. "

Adipex-P (phentermine) for Obesity: "I just started Adipex 3 days ago. I feel a big decrease in my appetite. I do feel very tired but, I'm wondering if that's due to no caffeine compared to all the caffeine I consumed prior. Not drinking wine and beer with meals is going to be a hard habit for me to break but, I need to do something. SW: 234 pnds 5'6 and 32 years old GW: 170 pnds I'm very embarrassed that I let myself get so heavy I'm so scared this isn't going to work for me. I went to a wonderful clinic in Southshore KY for the adipex. $100 for 2 month supply."

Adipex-P (phentermine) for Weight Loss: "I am a diabetic and in October 2016 I weighed in at 306lb so started adipex and by May 2017 I was 226lb! I am 5'9 so being 226lb means I wear medium-large. By no means is this a magic pill! I lost weight fast and it was due to taking adipex along with a reduced calorie diet (all clean eating) and working out 1hr 5x a week! I got pregnant right after my weight loss but I am ready to start adipex again and this time my goal weight is160-180lb"

For Weight Loss: "Am three days shy of month 1. Doc and I agree we will do 2 months on and then 3 tapering down. I went from 5’5 and 177lbs to 160.9 as of today. I work the night shift as an ER RN, so regular meals never happen, I was averaging 900 cal day for a week, and then the scale went up 1lb and didn’t budge for 4 days. Went over my food plan and realized I was starving myself, I wasn’t making time to eat. Past few days upped to 1300, and dropped 2lbs. Doc wants me at 1600-1800k BUT on work days that will NEVER happen as there’s nights I don’t have time to pee let alone eat. I have learned though that I need to eat at least 1200-1300k or the scale won’t move. Just remember once you come off the meds your body needs fuel. If you starve it now and expect to NOT gain weight once off the med then you are kidding yourself. I am 15 pounds from my goal, and when it happens it happens. To all you out there having a hard time seeing the finish line it is doable. Just remember to eat, don’t make my mistake."

Adipex-P (phentermine) for Obesity: "I started Adipex 37.5 mg 2 days ago, weighing 266lbs. I am 4'11", female, and only health problems are obesity and asthma (exacerbated due to weight gain). I am down to 263lbs (-3lbs) in 2 days. First day shortly after I took the pill, I felt sort of high and jittery. Wore off in a couple hrs. I took the pill earlier in the day yesterday (which I plan to do everyday moving forward) right before my workout. I had tons of energy. Didn't feel high or jittery, but maybe because I worked out shortly after taking the pill. I do have dry mouth, but not terrible. It has definitely caused decreased appetite. I didn't want to eat at all yesterday. I ate 2 small meals and a snack, and before I knew it, it was bedtime. I will be more conscious of my food intake moving forward. I'm pretty sure I ate around 800 calories yesterday. I will update after my next doctor's appt on June 19. I don't plan to weigh in again until then."

For Weight Loss: "I have also posted under the name Donna, and this is an update. I'm 54 yrs old and weighed 176.2 lbs (5'4" tall). I started this on 4/24 at 37.5mg dose. I wasn't able to sleep the first two days, so I cut the tab in half and take it between 7:30-8:00 am. In six weeks I've lost 12.4 lbs. I try to walk at least 4-5 times a week, not too strenuous just yet, I need to drop at least 20 lbs before I can do more aggressive exercise. I stopped taking it last week to see and ate out a lot over the holiday weekend and maintained, which is fine considering. I took 1/2 again today and will for this week to see if it makes a difference. I was still having issues getting to sleep even off the pill, so that is the most difficult part. I also get a little dry mouth when taking the pill and feel like I've had too much caffeine. Overall I'd recommend this, but there are some side effects, like the sleep issue that could be difficult for some people."

Adipex-P (phentermine) for Weight Loss: "I went to the Doctor on 5/17/18 I am 5'3" tall, 38 yrs. old and have had 4 children three of which are adults now, anyway my weigh in at the Doctor's office was 233lbs. I started my first pill 5/18/18 at 6am no side affects other than dry mouth and energy boost for me. I went to drinking only water nothing else that day I started the pill, I am using my exercise machine 15 minutes in the morning and 15 minutes in the evening. I have kept myself on a three meal a day program with low calorie intake and as of today 5/29/18 I am 222lbs I have lost 11lbs in 12 days. The first week I noticed that my weight was just dropping quite quickly but as this second week progresses I have noticed that my weight lose has slowed down and is stabilizing to a slow steady pace which is good or for me I feel it is. My goal weight is 115lbs. Hopefully by summer time 2019."
