I started G.I. diet couple of days ago and since then i am having awfull headaches!!!I can't be takeing every day tablets so i was wondering is that normal???I mean , is that only 'cause my body is getting adjusted or...??I used to drink lots of coke (diet one), but since i am dieting i completly cut it from my menu...So maybe that can be cause aswell...Does anyone have( or had) simmilar problem??Thank you...P.S. I do drink lots of water...
