Maybe my mom is right in saying that I damaged my system through my changes in eating habits and dieting...but I don't think that what I was doing was drastic enough for me to be going through this. The unbearable gas that I had while on vacation in Mexico returned and I am trying to figure out why...what did I do differently? what did I eat....I had an instant soup wednesday night, but does it take that long to take effect? (I also noticed afterward that it had lactose in it--could that be it?)...then because I was really constipated I took citrucel thursday night. This is awful...I just hope I'm better by Monday because I'm having three exams this week....God help me!
