Probably not but there is one piece advice I have. After you take whatever it is that’s doing the roto-rooter job, if you feel like you have to break wind don’t. Get on the toilet first and then try. (Ok, so I almost crapped myself because I felt like I had to fart and thought "I’d better get on the toilet, just in case.) Of course after the procedure feel free to break wind all the time.
Oh, definitely drink lots of fluid. I didn’t drink enough because I felt so bloated after the magnesium citrate I took for my cleansing which gave me a massive headache the morning of the procedure. (It made me so sick to my stomach I puked up the entire second dose of cleaner.) Don’t worry about the procedure though, they didn’t even knock me out for mine and it wasn’t anything to write home about. (They gave me some sedatives but I was totally aware. Definitely I should have watched on the screen to see what they were doing.)
