kid - one of the LAST things you need to be doing is taking dieting pills......SERIOUSLY - DON'T.......eat healthy meals, drink plenty of water, take a multi-vitamin and get some exercise and you'll be fine........OK ???
Twice a day.
Usually twice a day means in the morning after getting ready for the day and in the evening after dinner time
