I need some advice on a health problem that I have.About 3 weeks after having my son 4 years ago I began to crave sugar so strong that if I didn't eat something sweet I would shake uncontrollably and feel sick.I've been tested for diabetes and hypoglacemia and both were negative.Although I did test posetive for thyroid disease and am taking 150mcg levothroid.I have gained about 110 pounds and am absolutely miserable as I am small boned and the weight is very heavy on me.What could make me be so dependant on sugar especially since I never ever ate anything sweet before.I was always into fitness and nutrition and was in very good shape.Is there some kind of medical condition that could cause this?I try really hard not to eat sugary foods,I don't even like the taste but if I don't I become very sick.Please help if you can.
