I'd try to avoid taking stimulant laxatives like bisacodyl on the regular. From what I've read, they can eventually interfere with your colon's natural mechanism and you'll become dependent on them. I was using them from time to time at first until I ass-blasted a level-9 clogger into the commode, causing the need for swift plunger action. It was actually getting kind of scary at that point because I'd feel the internal pressure, but have such difficulty getting things to come out.
I started on the dosucate, which is not a stimulant and safe to take regular, but one a night wasn't quite enough. I then found the Miralax, which seemed to do the trick (and it's also safe to take regularly). Just gotta chug a lot of water with it.
Before I found the Miralax, I bought some saline enemas just in case, but thankfully never needed to use any.
