obesity
"I started Phentermine, prescribed by my primary care physician, and it has been nothing short of amazing in my case.  I started taking it at 372.4 pounds. Within a matter of 4 days of taking the medication I noticed a HUGE change.  This gives me energy, and makes me feel not hungry at all.  In 5 days, I lost  11.3 pounds.  I don't have any of the nasty side effects that everybody mentions, but medications affect people differently.  I take the Phentermine EVERY day at the SAME time, and am already noticing a difference.  Along with not making you feel hungry, when you do eat, it makes you feel full.  FAST."
