Ive been taking excell for about a week now (first time ever). The last couple of days ive been having some stomach issues ie-cramps, dirahea(sp) and some bad gas haha. Ive been eating basically the same food everyday and i was fine until i started the excell. Im wondering if it could be the sucralose in it, as thats the only thing i can think of. Any body else have any problems and or advice?
