"update! tomorrow will be a month i&#039;ve been taking phentermine 30mg a day. the dry mouth went away. i am pretty much feeling normal. i started out at 178 and lost four pounds in the first week. however then it has slowed down to 1-2 a week and i&#039;ll lose it, gain it back, and lose it again. i eat something small for breakfast, usually skip lunch, and then eat supper.  as of tonight i am 166. so 12 pounds in one month! i&#039;m only prescribed this for three months so i&#039;m hoping if i keep losing 1-2 a week i can be at about 150.  i&#039;m 5 3.  (my prepregnancy weight from my 6 year old is 112 and i don&#039;t intend to get to that again) second child is 5 months old and before her i weighed 160."
