"i started phen on march 23rd and weight 193.  as of june 27th, i weighed 169.  my goal weight is 155. (i&#039;m 5&#039;10&quot;) i took a whole pill for the first couple of weeks...but, experienced extreme side effects - jitters, cotton mouth, breathing irregularities, constipation etc.  i decreased my intake to 1/2 pill every morning and the side effect were more manageable.  i now take the weekends off on the pill and exercise when my schedule allows.  i eat extremely clean...except for a couple of glasses of wine every now and then.  i&#039;ve also gotten the lipo shot 3 times since i&#039;ve been in phen."
