Juniper,
I am sorry you aren't feeling well.
...stomach issues are the worst.
I would give your Prilosec a week or so to become beneficial before making any decisions.
This also gives you another week to get past start up effects from the A/D's. Some people need up to 8-12 weeks for this.
I am sending positive thoughts and prayers!
Keep up the good work, and know we are cheering you on.
S.C.
