I'm suprised no one knew theser 3 things.
1. Butt burn is common, the materials are still acidic it is not the be all to end all but a bidet like the ones in the following link.
Can make a huge difference in your everyday life. Yes I know you can only use it at home but that much is a huge improvement.
2. Codiene slows the digestive track down where things like Imodium generally work by removing water from the large colon. Duh! we do not have large colons any more. It may not be for everyone but I genrally sleep thru the night getting up maybe once or twice. I still go the bathroom up to 20 times a day.
3. Cortisone cream takes care of the dry skin patches that show up but they will always come back so just key a tube around to deal with it.
Please try these things if you have the issues don't suffer for nothing.
