I don't feel very well... :(

I just started IF#1 and #2 yesterday... I didn't start the #1 ahead of time because I normally have 3-5 bm's a day.. (although, mostly very loose.. pencil thin, and some diahrea)so, since I am already at the recommended frequency uny recommends, I just started right in with the #2.. (and took one if#1 last night)... I will continue to monitor, and up the IF#1 as needed.. so far, though.. my bm's have been right where they should be as far ad frequency..

I did 5 shakes, total, yesterday.. got all of my water in.. took one of the IF#1 last night... and I'm on my second day today, and I really feel awful... I have a horrible headach.. sick to my stomache.. I'm tired, and achey... yuck.. I don't want to lay down, as my head hurts more when laying down.. yet I don't have any energy to do anything else... :(

why do I feel so bad?
