I've lost 9 pounds in a lil less than a month and im super happy with that! Ive always gained weight over Thanskgiving, so I'm exctied that I finally lost weight this year!

Just finishing my first month of Qsymia and I'm excited to get my refill for month 2!! Ive been eating healthy, plus going to the gym most days - doing weights and the elliptical when i can. I started at 209 and I'm already down 11 pounds to 197! First time I've seen that scale below 200 in months :D

The only bad part is that my insurance doesn't cover it, so it's super expensive... but if it keeps working its worth it!!

Phentermine gave me Colitis. Have to see a Gastroenterologist now every few months. Now I am on medication because of my Colitis. I wish I never meet that diet doctor. That Phentermine pill ruined my life. Yes I did lose weight on the phentermine pill but it wasn't worth it. Now I have to have a colonoscopy every three years. I have to know where the bathrooms are. I can't enjoy going out like I did before. Read less

I started taking 15mg of Phentermine on 7/28/17. I had no side effects and it wasn't suppressing my appetite after around 2:00 pm. I took it first thing in the morning around 7:30 am. I continued taking the 15 mg until this morning (8/1) because I wanted it to work and had read all about people not being hungry at all. This morning I took 2 15 mg capsules. It's 3:30 pm and I have not been hungry all day long! Side effect is dry mouth, which is great so I can continue to drink lots of water. I am a female 5'4" and on Friday I weighed 164.6 pounds. This morning I weighed 162.4. 2 pounds in 4 days. I'll keep it up and see how it goes. I only have about a 30 day supply. Read less

My doctor asked me at my follow up visit do I still get really hungry and I replied yes. She wrote me a prescription for this medicine and told me to start taking it right away because I wanted to get scheduled for my Bariatric Surgery. In order to be considered for the surgery I needed to lose at least another 10 pounds. I started taking phentermine on January 25th. I lost 8 pounds in one week. Today is February 10th and I have lost over 20 lbs. This stuff is amazing. A little dry mouth. Never hungry. I am scheduled for my surgery and excited. I recommend phentermine to anyone that really wants to lose real weight! Read less

I've been on phen for about 2 weeks now and I've lost 7lbs.
Preface: I have bad anxiety and occasional depression. I weighed 115lbs in college. dated, got married and ultimately had a child. I started Phen at 164lbs.
Current: I love how its curbed my appetite which makes it so much easier to make healthier food choices which in turn, is turning into a habit. I did skip 2 doses due to excessive anxiety or just got so busy with work I couldn't stop to eat so I could take my pill. During those days I missed, my appetite wasn't as suppressed but I still had cotton mouth.
Side effects so far are occasional mild headaches(i suffer from migraines so these are a breeze) dry mouth, irritability(nothing really new or uncontrollable) I am more forgetful. I drank coffee and energy drinks for so long that the palpitations are a normal thing. Like a tolerance.
I have noticed a decrease in effectiveness after the first 2 weeks. My stomach growls when I'm hungry otherwise I wouldn't know when to eat. I still crave sweets but its so much easier to refuse now.
I've cut all soda and greatly decreased unnecessary sugar intake, decreased carb intake such as breads, chips and other snack foods. Made a complete overhaul on my diet choices. I need help drinking water despite the cotton mouth. Oh, another weird side effect is yawning even though I'm not tired. I have absolutely no problem sleeping, but I did notice I need a nap during the day.
