"i started phentermine this am at 9, dr put me on 15mg per day. well i don&#039;t do drugs cause they scare me, and so do the side effects.  so i pulled the powdered capsule apart and sprinkled 1/2 the powder into my coffee. i&#039;m a sipper so i just keep sipping all day long on a beverage of my choice. around 11 am i went back and sprinkled the other 1/2 of the capsule on my coffee again. i wanted to get the rest of the pill down before 3pm, afraid of the side effect of insomnia. i already have insomnia pretty bad, i just can&#039;t shut off my brain. i will keep splitting the pill to see how i handle the side effects if any. i can say without a doubt, this pill does control your appetite. i am still not hungry,  and very very excited about my journey."
