obesity
"I'm 50 yrs. old and just started phentermine 37.5 mg. 2-16-16.  It's just been 4 days and I've already lost 14lbs.   I'm 5'8 and started at 320lbs.  I wanna get down to 145 so I have a long weigh to go but so far.  Wow!  The only side effects so far is dizziness, jitters, constipation and, slight headaches.  All of that I can deal with because this pill is working so far.  Will update in a month or so... T.L.B. in GA"
