The only real side effect I'm getting that I can't handle right now is indigestion/heart burn. I've been taking two extra strength Zantacs in the morning and at night, and Tums as needed. That's kept the heartburn at bay but now I'm not digesting my food properly it seems. I was in the middle of my cardio session tonight and had to stop to go and puke in the bathroom.. Anyone else have this kind of issue and how did you resolve/work around it?
