Again, just keep sipping water. I know it can get crazy boring so try and sip different things.....ice tea with splenda, crystal light, juice cut with water, ect..... I was also really dehydrated after surgery and i had to FORCE myself to drink. Also, for the swelling....it'll go down on it's own, but I noticed that the more movement I did the faster it went down compared to some of my friends that got banded with me. Also, if you walk and exercise you'll want to drink more, so it helps on both ends. Good luck!
