Will I Ever Be Able To Chug Water Again? in POST-Operation Weight Loss Surgery Q&A Posted August 29, 2012 I'm 5 weeks post op today, and I can tell you from my experience, it is a whole lot better today than it was 3 weeks ago. Hell It's better than last week. I've started working out since last Monday, I get very thirsty so I take a good size gulp just to have it in my mouth and then just swallow slowly. Usually like to swallows and its down. But it really seems to quench my thirst. Good luck- it gets better and easier!!
