"several years ago, i took phentermine for 9 months.  i lost 75lbs, my hair, and my ability to sleep.  i had extreme insomnia for several years which then turned into major anxiety.  it took me about 5 years to get a full head of hair back...i had bald spots all over, and i am back at my original weight.  my husband told me he would divorce me if i went back on it.  i became a food nazi and could not sit still...basically my family hated me.  sad thing is...here i am looking into phentermine again because i hate my weight."
