Bathroom TMI

I have been having acid reflux for the past two days.  Plus, my bowl movements have been green tinged for about a week now.  This means there is extra bile going through my system.  I am disappointed, because I was told having the gastric bypass should help with this.  I am worried the excess acid is going to give me an ulcer where the inside incisions are healing.  It got so bad last night I had to take 2 generic Tums.  Those hurt my stomach making it feel almost like it was too full of gas.  Then this morning, I had burning butt hole as the acid left me at the other end.  I'll be calling the doctor this morning as soon as his office opens.
