For Weight Loss: WOW is all I can say I started the phentermine 37.5 on 03-07-2014 my weight was 217lbs and I weighed myself today (03-13-2014) and my weight is 197lbs. I have lost a total of 20lbs. This has changed my life, I have always struggled with my weight since 2008. I have never been under 200lbs and now I see the scale it makes me want to cry THANK YOU SOOOO MUCH Phentermine. My goal is 150lbs for the summer.

For Weight Loss: Lost 9 lbs the first week but I am very irritable and my moods are very unusual hoping it will go away as my body gets used to the medicine.

For Weight Loss: I started phentermine on 3/1/14, my starting weight was 205lbs. I have been steadily going up due to medical issues. At first the side effects were foggy brain and the jitters. Shortly after the first week had to have my gallbladder out so had to stop. Started medicine again, with being on medicine for a total of two weeks I am now down to 193lbs, that is a loss of 12 pounds of just two weeks. Very excited and happy with so far.

For Weight Loss: I started taking phentermine on 3/1/2014, I weighed 179 pounds, after only 10 days, I've lost 9-10 pounds. Which I'm ecstatic about. I haven't had any of the side effects that I read about, other than the dry mouth, which is also great. I wonder if that means I'm not taking as high of a dose as I should be. I'm only 5 foot 2 inches. Within these 10 days, the first 7 days I lost my 9-10 pounds, nothing has changed since and I don't know why? My appetite had decreased and I work out 5 days a week for 1.5 hours..what's the deal? Does anyone know why I might already be at a plateau? I'm excited to have lost the 9-10 pounds, but I'm slowly getting discouraged again because more weight isn't falling off..... help.

For Obesity: I started taken phentermine 37.5 on 3/5/14 and my weight was 241 lbs and on 3/10/14 I had lost 5 lbs down to 236lbs. This week I plan to increase my exercise and hope to lose 5 more pounds by next week. I have not experienced any problems sleeping but the dry mouth is all day but it has made me drink more water than I usually do. My goal is 170lbs hopefully by May.

For Weight Loss: Started phentermine January 15, so almost 2 months ago. I'm 5'2 and my starting weight was 151lbs. I'm now down to 126lbs! Lost weight really fast during the first month (about 20 pounds). Weight loss slowed during the second month but I wasn't eating quite as healthy as the first month. I'm trying to lose 10 more pounds, so we'll see how it goes! I have a little over 2 weeks of phentermine left, so hopefully it will help me.

For Weight Loss: Started phentermine on 3/2/14 and I am so excited about the new me that is going to emerge- after reading all of the stories that have been shared about weight loss with this medication I am super excited- for the last two days I have had to make myself eat and to my surprise I haven't even had a second thought about any fast food or junk food and that my friends, is saying a lot right there. I was weighed on 3/2/14 in at 303lbs and I am 5"9"- 37 years old, 1 daughter who just made 18 and I am single- sounded like a perfect time for a lifestyle change- my goal weight is 170lbs by October of this year- I understand that I have set the goal extremely high but its something that just has to be done. Wish me well and kudos on your shared success.

For Weight Loss: Began taking the 37.5 mg version on 2/23/14 and I've lost 7.8 pounds in 6 days--tomorrow will be one week. I've gone to the gym 5 of the 6 days for 50 minutes of elliptical workout. I've been eating just under 500 calories a day, and I have to make myself eat because food doesn't seem appealing at all--it's the weirdest thing. I take my pill at 11 am and have no trouble falling asleep around 10:15 pm. Will post again next week with more details. I'm 5'7 (and 1/2) and started my diet at 191.6 pounds.

For Weight Loss: I started taking phentermine on February 14, 2014, Since then I have lost at least fifteen pounds and it has not even been a whole month yet, this is awesome, I work night shift so it keeps me up all night and gives me plenty of energy, I hardly ever get a chance to work out because I have three children that crave a lot of attention, this stuff is the best thing since sliced bread! I don't think about eating, I will force myself to eat a little bit of something healthy every few hours, the side effects were scarey the first two days but after that my body pretty much got used to them. Anyone looking to lose weight this is most definitely a jump start way!

For Weight Loss: Been on phentermine 37.5mg for 2 weeks and I'm down 16lbs. My fast food cravings are nonexistent, I almost have to remind myself to eat every day, I have the energy that I didn't have to keep up with my 2yr old daughter. I've tried any OTC supplements you can think of and had no luck. I go to the gym for an hour, 4-5 days a week and didn't seem to get the extra weight off. This pill with a regiment of B12 and lipotropic injections gets the job done. As for negative effects... Only complaint is the cotton mouth. Other then that there is nothing bad to say. The energy high is amazing. Of course the B12 helps as well.

Adipex-P (phentermine) for Obesity: I tried Adipex before I got pregnant with my third baby, and I lost almost twenty pounds in a month with this combined with Atkins diet. I did notice that my body started getting used to them so on Monday when I get them I will only take them five days a week. I really hope they help me again I really want to wear a bathing suit this summer.

Fastin (phentermine) for Weight Loss: I just started using Fastin and I like it better than other diet pills I've tried such as Hydroxycut because it doesn't make me feel sick/ nauseous. BUT it definitely makes my heart rate skyrocket, so for the first couple days I would only take half a pill at a time. A full pill makes my hands tremble and I can hear my pulse in my brain.

Review by BusyBE (taken for less than 1 month):

Adipex-P (phentermine) for Weight Loss: Update after 7 days: Starting Weight: 161.4lbs Current Weight: 158.4lbs I started off taking a 1/2 tablet in the morning, 30 mins before breakfast. First few days were okay, took the edge off hunger for sure, but I felt unfocused. On day 5, I traveled out of town and started feeling a little nauseous, so I held this medicine on days 6 and 7. I slept so much these two days and was very hungry. I was just so relieved to not be nauseated that I allowed myself to eat some not so healthy foods on these two days. This is partly why I do not think I lost much weight this first week. I started back on my 1/2 tablet regimen this morning and feel quite good. I think the nausea may have been related to a certain food I had eaten.

For Weight Loss: This is my second review, last time I commented I was at 205 LBS and 11 LBS lost in two weeks. At third weigh in on 2/22/14 I lost another 4 LBS and now weight 201lbs. I went from 216 to 201 in 3 weeks. I would say yes, phentermine definitely works to curb my appetite. My next weigh in is March 1, 2014. I hope to be under 200 (fingers crossed). I don't want to get my hopes up since I've already lost "a lot" for the first month according to my Doc.

Adipex-P (phentermine) for Weight Loss: Day 4, taking 1/2 tablet of the 37.5mg. Decreased appetite, more energy, some dry mouth here and there. I've noticed at some times a decrease in concentration, like a foggy feeling. Nothing too bad, but a little off my baseline. Haven't weighed since day 1. Hoping to lose 15 lbs this month. I like that I don't feel "cracked out" but I am hesitant to up my dosage yet. I'll keep taking the 1/2 tab until I get really used to it. Once I reach my GW I plan to wean myself off in the same way. Will update. -BusyBE

For Weight Loss: I am 61.5 inches and I weighed 179 at the first Dr. apt. for 41 years old that is not a good place to be but with the medication I am hoping to drop 30 - 40 pounds... First day I had absolutely no appetite, was awake longer than normal but I did finally sleep. Day 2 I still had no appetite but I did force myself to eat little bit easier of a time sleeping still up later than I wished but once I fell asleep I was out. Today is day 3 and I weighed myself and I am down 173lbs, 6 pounds in 3 days I am Ecstatic! I have been exercising by doing Zumba and lifting weights it is amazing to me how much energy I have. I can do an hour of Zumba. I sweat like crazy so you need to remember to drink a lot of water. Hope to meet my goal in no time.

Adipex-P (phentermine) for Weight Loss: I love love love Adipex! It took me about a week to get used to all the side effects but when you realize how much weight you are losing the side effects aren't even in your mind anymore, I started taking Adipex Jan 24th 2014. Weighing 210 pounds. Today is now Feb 19th not even a month later and I now weigh 185. That is 25 pounds down in just one month. I work out (run a mile, ellipitical, 20 min abs) 5 to 6 days a week and I only eat 1000 to 1300 calories a day! This pill is amazing and everyone needs to try it, that is wanting to lose weight.

For Weight Loss: Really has not reduced my appetite. I have tried this for 30 - 90 days, 3 different times. I also get a side effect that is not listed, but after the 3rd time using this, I'm 100 % sure that it causes a sensation of burning on the tip of my tongue. It stops after a few days of not using the medication.

For Weight Loss: I started using phentermine 30mg on 2/1/14. My starting weight was 216 (I'm 5'3")...on 2/8/14 I weighed in at 209 and on 2/15/14 I weighed in at 205 (while on my period, which usually makes me gain 4-6 lbs) 11 LBS in two weeks is soooo motivating. I was recommended the Atkins diet but I workout really hard (power lift, insanity, boot camp) so for the past two weeks I didn't do the practically no carb plan I was given, but I did lower my carbs significantly (I used to eat a lot of oats, wheat bread, sweet potato) the doctor said I'm doing great because most people my age, height, and starting weight, lose about 10LBS a month. Phentermine curbs my appetite like nothing ever has and I'm loving my results so far. I'll update next week.

For Weight Loss: I'm on phentermine for the 4th time. I told my doctor I want a life long IV drip of the stuff. It's a miracle in a bottle. It cured my sluggish tired feeling days...made me up beat, happy, motivated for daily tasks (which are many with four small children) not to mention it not only suppresses physical appetite but the all powerful emotional appetite. My brain quits telling me I need food to feel better! I've lost a lot of weight on phentermine. Here's the catch. You can't stay on it forever. Being that I'm on round four ...hopefully I can keep it off this time. I have also experienced the dry mouth and heart palpitations (hopefully harmless). Be strong when you are done and don't gain it back!

For Weight Loss: I started Jan 4th at 262lbs, weighed in at 253lbs. I hike every weekend and dont snack as much. I try to eat low calorie soups for lunch vs sandwhiches or hamburgers. I still need to modify my breakfast to a lower calorie version. So far, I'm okay with it. I need to be 180lbs and under.
