Ok so, I have had bad experienes with this. I have hypoglycemic, hypogly. messes with your thyroid already. Well, the doctor seemed to have overlooked the fact and put me on the shot that could mess with your thyroid levels. I have been on it for about a year and a half, and everytime after i take the shot I get syptoms of really low blood sugar everytime, I believe one tmie my blood level was at a 73! I havent gained any weight, but it seems like my abdomin isnt toned anymore. I also have mood swimgs like the rest, I will not be taking this shot again. btw:i have noooo sex drive
