"i took phentermine in 2002 on and off and lost a lot of weight. i started again on tuesday 24 june. i currently weigh 195lbs and am 5ft 7. i wanted to ask people this forum who have had a good weightloss if they took the tablet or capsule and also if they have changed their eating habits and if they count calories? when i took it years ago i don&#039;t recall eating a lot, but now i was told i need to eat 1200 calories in order for it to work successfully. is this correct? thanks in advance for reading and responding."
