weight loss
"This is the second time I have gone on Phentermine 37.5 mg.  I took it back in 2013 on and off for 3-4 months and lost about 22 pounds.  I am 5'2" and weighed about 156 when I started, 134 when complete.  My big mistake after going off it was to start eating like I did before starting.  Being menopausal, it's so easy to eat whatever looks good.  My best advice to everyone is to remember that once you go off of it, you HAVE to alter your old eating habits or you will have wasted your time.  Now I'm back on it again this year, almost done now.  This time I went from 153 in April to 128 now, and I'm going to work hard to stay there.  My worst side effects both times were dry mouth and constipation."
