I cam home yesterday afternoon. Sleeved 10/17. I have a lot of rumbling too. part the rumbling is all the excess air in your belly. Walk, walk,walk they told me. Well, my new best friend has been my hot water bottle. Way better than a heating pad, because you have some pressure as well. I laid down with it, and the gas just kept creeping out all night. I'm glad I decided to use ir over a heating pad. As for hydration, everyone is different, but sf popsicles have been my best friend. Edy's are the best, but walmart sells some for $2 that are real good. Decafe cold tea with lemon has been great too. Remember your belly is healing and cold does help relieve inflammation. As far as sleepy, I believe the narcotics were my issue. Now I just take liquid tylenol. BIG DIFFERENCE! I hate feeling loopy and groggy. Well, I hoped I. helped a little. Good luck to you!
