"i started phentermine right before thanksgiving.  i am 5&quot;2&#039; and starting weight was 184lbs.  it made me not hungry at all.  i constantly drank water and ate very lightly.  no insomnia first month.  i lost 17 pounds.  second month i had to take 3 days off because of the insomnia.  if i feel i can&#039;t sleep i will skip a day or two.  still only drinking water and eating lightly.  no exercise at all and today i weigh 156lbs.  total loss of 28lbs in two months.  this month i plan to add exercise to drop more weight. love phentermine!"
