7 days post bypass. How are you progressing?

I am 7 days today revision from sleeve to bypass, hiatal hernia repair and gallbladder removal. I have had a rough time getting my fluids in and a lot of stomach spasms. The day after surgery in the hospital I did great. I drank fine went home second day no problem. But them I started have stomach spasms with cold fluids and my protein drinks. I couldn't get my fluids in and got dehydrated. I am doing better with getting fluids in, but I had a bad 3 hours bout with spams last night for unknown reasons. I go to the doctor tomorrow and I am hoping to move forward to pureed but I am nervous about having more problems with my pouch not liking it I never had any issues with spasms with the sleeve only just felt full. Anyone in pureed yet? Anyone having trouble with spasm? How do u feel the restriction? Do you just feel like you are full?
