"this is truly a mind altering drug. takes the lust with food out of your mind. i had difficulty the first two days i went from 3/day to four..so i backed off to 3 again for another week and then did fine when i increased. i do have headaches, but i have never had the nausea ppl talk about except for the day i increased to 4. i have asthma and hypertension. both are doing well on this drug. i have lost 11.9 lbs in 5 weeks. i do not feel deprived. i still enjoy an occasional sweet treat, and have still lost weight on those days. the main thing that i have eliminated is snacking. i really don&#039;t have any desire to do that. i drink a lot more water now too. this drug does seems to give a dry mouth.  very happy with this drug."
