I don't know much about the dosage question. I would have to see the bottle but if they are caffeine pills I would tell you not to take them. They really aren't good for you and yes they will make you so jittery. Take it one day at a time and try to make the best food and exercise decisions you can and slowly the weight will come off. When you take it off fast it never seems to last. Take care of yourself, have a great Tuesday and sorry if I wasn't any help.
