For sleep you can take Tylenol pm my doctor recommended it to me. Nd ilk of magnesia is for constipation. Try some regular milk or alka seltzer
Try cold stuff, ice, ice cream, I know Popsicles are the best... and try not to drink anything a hour before bed and as far as sleeping try putting a pillow against your tummy I have the same problem but conform from the pillow helps me
I would get the alkiselzer ( hope I spelled that right) the chews for antiacid they work wonders. As for sleeping I like to put a pillow under my leg and I don't drink water before bed.
