Swallowing liquids
I remember in the beginning I could only sip liquids. I wasn't able to drink normal for quite awhile. As for diarrhea, keep an eye on it. You don't want it to last for days. This will definitely dehydrate you. Mixing gatorade and water would help keep you hydrated. Gatorade by itself is a bit strong but if you can tolerate it than go ahead and drink it straight.
