Go to a nature food store... they might know how to give you something but it sounds close to you may have a thyroid problem. Go see a naturalist... better than western tablets for that sort of thing from what i've hear.... and walk deeply... a few kilometers a day... sweat it out... do a body cleanse and sweat, sweat, sweat. It's harer for some than it is for others but if you wanna look perfect and feel great give or take a few yourself then do lot's of exercise stay away from starchy foods resembling rice, potatoes, sugar, and pasta... they do nothing but turn into body counterbalance. Good luck!
