"started phentermine 37.5mg in april 2014.  i have lost a total of 25.6lbs to date. the key to doing this right is watching/tracking what you eat/drink and finding a workout routine that works for you.  i elected to join weight watchers because i walk to be help accountable by someone other than myself.  during the last 4 1/2 months i&#039;ve never had a week that i&#039;ve gained.  i have stayed the same 5 separate weeks but no loss is better than a gain to me.  i travel a lot for work, so food wise, it&#039;s all about choices.  just because you&#039;re not hungry remember to eat at a regular scheduled time if possible.  don&#039;t go all day without eating.  losing weight to fast may make us happy but it&#039;s not healthy.   good luck everyone."
