"i have been on phentermine 37.5 for 44 days, have another 46 to go (90 day supply).  i started out at 305.  i have been walking every other day for 2-3 miles, eating only fruits/vegetable throughout day- then a normal dinner (even pizza/burgers).  after 44 days, i&#039;m down to 274, with eating a relatively normal diet.  with the dry mouth, i drink more water, been feeling great, sleeping good, as long as i take the pill first thing in the morning!"
