"i ave used bontril for about 2 weeks right now and wow! i went by the diet that my wonderful doctor gave me and even without exercise i have already lost 23-25 pounds! i am severely overweight so i know these results aren&#039;t typical but when you weigh over 300 pounds every little bit makes a big difference! the only major side effect i have had is a few heart tremors. once you get in the mind set that you don&#039;t need a snack cake or pastry in your mouth every few minutes then you can feel good not only about your weight loss but also about the great choices you are making!"
