"Update so I started taking this on May 19th, 5ft tall and 250 pounds. I felt dizzy my first three days and ate very little. I try to eat less than 1200 calories a day. Some days I'm still hungry though. It hasn't even been a month and today I weigh 224. That's 26 pounds in 27 days almost a pound a day with no exercise. The results for me have been amazing. I do have trouble sleeping so I usually take the pill earlier in the morning. I take a whole one a day. I also have had severe dry mouth mainly the last 3 days but I'm also taking a water pill."

"Started on Tuesday June 6, 2017. Staring weight was 278lb (126 kg). Today is June 8, 2017. My weight is 269 (122 kg) I also got a B12 shot but it made me sleepy. Has anyone every experienced this? Next Saturday I'm going to try the Lipoden shot. I also went for a two mile walk yesterday and I plan on walking everyday and going to Zumba as well. I started a new job and there's an on site gym. So on lunch I might jump on the treadmill or walk around the building. I'll keep posting updates on my progress.."

"I started this pill April 13th 2017. I am 5'3 and starting weight was 199. I am also turning 27. So far my weight as of today is 186. At first I was really seeing some weight shed when I stepped on the scale and it kept me motivated. Now, not so much. I keep teeter tottering my weight each week. I gain a point, loose 1.2 lbs. gain another lb, lose 1.4 lbs and so on. This has been happening for the last 3 weeks. I'm discouraged seeing so many people losing 10+ a month where I'm almost on two and only down 13 lbs. is this normal? Idk what I'm doing wrong. Is a temporary and will kick in again where I lose more rapidly? Idk what to do. I am going to quit by all means, but I do need some encouragement. I see the doctor tomorrow. Will see"

Adipex-P (phentermine): "I work at endocrinology clinic. And there I have seen crazy stories about Adipex-from 191 lb in 1 year to 30lb a month. So, I said to myself I'm going for it. In first 3 days I am 4lb down. I have plenty of energy, I do have a dry mouth and one time after I stood up from the bed I felt dizzy. Now my post is more for the people who are taking it- plz take 1200 cal per day. If you take less, you will have jitters and you would start doubting the med. And yes, I push myself to eat, because I want to eat, but I eat small portion. From day one I want to adjust my portions, always small portions. After 1 months after my med finish, I will continue small portions and wont pass the 1200 cal. Good luck.."

"Hello everyone. I'm a 30 yr old female. My starting weight is 396. I went to the Dr looking for help. He gave me a choice between 2 meds ( phentermine and contrave). I choose phentermine. I started taking the pill on May 4, 2017. He suggested I start taking half a pill just in case it would speed up my heart rate. After 3 weeks of taking half of pill I started taking the whole pill. I've been on the pill for a month and I have the most energy. The scale says I'm down 19lbs!!! My clothes pretty much fit the same but I can feel I difference in my walk. My back ache is no more. I can stand and have conversations at work without looking for a chair or leaning against something. I have changed the way I eat also. I cut out fast food."

"37 yo, mother of four children; 18y, 12y, 2y, 10 mos. I've been overweight then obese pretty much all my life. The older I get, the harder it is to try to lose weight it seems. My Dr. put me on Phentermine 37.5 last week. As of that appointment on 5/25 my starting weight was 260lb. As of 6/2, my current weight is 252lb. it's a huge challenge to try to eat as my appetite is GONE this first week. It's slowly coming back. the energy boost is great and much needed with 4 kids!"

"I took Phentermine about a year ago and successfully lost 50 lbs in 3 months ( losing most of the weight in the first two months and hitting a plateau in the third month). It got rid of cravings and hunger ( I had to set reminders to get myself to eat meals), increased my energy significantly ( I have Hashimoto's and lack energy), and of course lost practically all the weight without extreme exercising. I did do cardio and use my Bowflex during the week, but nothing compared to going to the gym. I was going through a few things for a while and ended up gaining back 30 lbs. I just started back on just HALF a .375 pill and losing 3 lbs a day right now. I have 0 negative effects. HIGHLY recommend."

Adipex-P (phentermine): "Hello!! I'm back! I start this medication on 3/31/17 with the starting weight of 213lb and as of today 5/25/17 I now weigh 186! I don't know about y'all but I'm happy! When I first started this medicine I was full of energy but now I just feel like a normal person. With me feeling like that I thought the medication wasn't working anymore but I was so wrong!! It still works!"

"MARIE501 I wanted to share my first day on Phentermine. I weighed myself this morning at 225.8. I am a diabetic Type 2 and my A1C levels are 13.3! Yikes. I tried the Low Carb High Fat diet and it worked. I lost 8 lbs in week, but it was extremely difficult to continue. How I feel: This morning after taking pill, I could barely eat! I feel weak, but also energized (weird). I am having dry mouth, but not severe, and blurred vision. Im extremely excited to see how this works for me. Hopefully the diet treats me well. Tips: Make sure you start on like a Thursday or Friday or weekend, that way you can experience the symptoms at home rather than work. CW : 225 1 GW : 200 2 GW: 155 I will update you guys next Friday"

Adipex-P (phentermine): "I have tried everything I could to lose weight from pills, to shakes, to teas, to detoxing, to even a lap band, and NONE of it worked. I had hit my all-time high of 230. I went to my fertility doctor and she said I was in bad health to try to have a baby. My cholesterol was high, my blood pressure was high, and to make it worse, I was pre-diabetic. I've been on adipex now for a month and a half. I've lost 35 lbs, barely exercise, but I'm so full of energy that I've completely redone my house, cleaned the garage, and refurbished lots of furniture pieces. I LOVE IT!!! I've not had his much energy since I was in my 20s! I do have about 20 more lbs to go and it will be off in no time."

Adipex-P (phentermine): "I originally weighed 374 pounds, and I got all the way down to 304 on my own by excercising. Unfortunately, my weight picked up and I hovered at 320 for years. I became so tired and desperate, I called the doctor fearing weight gain. She put me on Adipex in March, I lost 27 pounds the first month, 12 pounds the next month, I'm still working on my third month for final tally. I am down to 287. Although there were some side effects, the health benefits far outweighed the risks for me. My blood pressure dropped 40 points in the first month alone and I am no longer pre-hypertension. This medicine has been a clean slate for me as I cook my own food and retrain my body to be nourished."

"Been taking phentermine 37.5 mg since April 14 2017 since I'm morbidly obese. My weight was 258lb and I'm now 237lb thats a total of 21 lbs down within a month. I walk every evening for 45 minutes and stay away from highly sugar drinks, breads and greasy fatty foods. My goal is to lose another 40lb by August 15. First week on it I lost 8lbs then following week another 5 then went down to like 4 lbs the following two weeks. I still see it as really good. Went from a jean size 20 to a 16 now. I have been receiving weekly B12 shots for energy. Thats really helps me to staying energetic and active. Definitely a good pill for weight loss."

"So I'm taking phentermine 30mg. I am 5'4" 28 years old starting weight 250lb. I'm currently 220lbs. And I've been taking the pills for a month and a half. Dieting by eating 4 small healthy high protein low carb meals a day and lots of water, there are absolutely no side effects for me. Amazing energy through the whole day until bedtime. Will update at the end of my 3 month. "

"Today is my first day. 5/11/2017. I was told me to take it around 10:00 am as it could cause insomnia if I take it in the evening. I took it at noon.I had been procrastinating all morning. I'd done research and read all of the side effects. Even after getting the RX filled and placing the pill on my napkin next to my oatmeal I was still undecided about starting this med.I'm 246lbs and 5'2. Morbidly obese. I'm tired of being fat so what the heck, let's get this party started. I swallowed hard about noon. 1:30, I was jittery and sleepy.2:30, I had to walk around to keep from laying my head on my desk. As soon as I got home, I took a nap. Where is the promised energy?"

Adipex-P (phentermine): "I've been on adipex for 11 months now and I've dropped 117 pounds! I didn't exercise only took the pill and cut out everything bad (even though it taste good, doesn't always make it healthy for you) eating wise. Sugar, flour, bread, pastas, FASTFOOD, and even eating after a certain time. I started eating healthy snacks every two hours, ( egg whites, cottage cheese, bag of steamers vegetables, lots of chicken, belvita snacks, carrots and peanut butter etc,and drinking lots of water! Do this and I promise you'll drop weight immediately."

"I was 312 pounds when I started taking Phentermine 37.5 mg 11/2016. I took it for two months and only lost 12 pounds. I missed my appointment in February because my mom passed away. I went back to the doctor and and weighed in at 306 pounds on April 6, 2017. Today is May 7,2017 and I am 300. I lost down to 299 but have gained a pound because I haven't been drinking water and I haven't been active. Overall I have lost 6 pounds in a month. That isn't bad for not exercising. The medicine is wonderful but I am experiencing extreme dizziness to the point I am nearly fainting. I believe I need to drink more water. I have taken this medicine before and never had this problem but I believe it's because I am dehydrated. Drink water!!!!!!"

"I started Phentermine 37.5 on Sunday, April 30th 2017. I am 5'6 and 210 lbs. My issue is that a year ago I started a desk job and I packed the pounds on quickly. I have always been a bigger person but I have never been this big. I always thought about food all day - wondering when and what my next snack/meal was going to be. I should mention that I have been splitting these pills in half per my doctor. The first day I took it I had lots of energy and no appetite. Like a switch flipped in my brain and suddenly I wasn't thinking about food and my stomach wasn't growling. I never eat breakfast, just drink my daily coffee and have been eating a fruit cup from lunch and then I eat dinner as usual with the family. I've lost 4 lbs so far!"
