weight loss
"This is my second time using phentermine in 2 years. The first time I lost 30 pounds in 5 months, but the side effects were terrible the first time around! I would sweat just sitting down, I was jittery, dizzy, and had headaches. 
I gained back about 15 pounds since then, and decided I'm going for it again. I was expecting the same symptoms to come back (I have the same dosage as before) but  side effects this time!! I got the generic phentermine, and I like it WAY better! All it has done is decrease my appetite, and give me energy. No dizziness, or getting sweaty, or feeling like your on some crazy drug... just appetite control! I started at 254, and four days later I'm at 247!"
