"i use only 15 mg (doc prescribed 30 but i could not sleep at all with 30 mg, also it was so strong i did not have appetite at all and i would take only 300 calories per day if that much).so 15 mg works for me. i count calories i do not fo over 1400 per day, i run/walk 30 minutes per day, drink one gallon of water and eat everything in small portions like 5x per day. my snack is apples or almonds but i also eat sandwich once in a while or spaghetti or rice. the only thing i do not consume is chocolate or any other sweets. my carbs come from fruit or baked potatoe or corn... i went feom 246.5 to 229  since august 1 ( so in 25 days almost 18 lbs). i will probably lose few more until monday so i think total.of 20 lbs per.month is great."
