Joe, both pedialyte and coconut water are great ideas.
Can you get some marshmellow tea ( not from fake marshmellow, but the real herbal stuff), and put some d-ribose in it?
Marshmellow tea is very soothing to the whole gut and intestinal areas, and d-ribose is a basic sugar necessary for atp functioning of the cells.
Rx meds didn't help me. But 4.5 mg LDN +Paleo diet +supplements=REMISSION.Protein shakes w/almond milk,Maca powder,L-Glutamine,D-Ribose,chia seeds.VSL#3,K2,VIt. D3,slippery elm bark powder.For more info,my protocol is the 11th post at this link: https://www.healingwell.com/community/default.aspx?f=38&m=1666318
