Constipation/Diarrhea, confusion?!?

Hello.

Normally I have Regular/Constipation symptoms. At some times it can be very uncomfortable, so if it gets very bad (which isn't often) I take Polyethylene Glycol (Mira-LAX) and stool softeners.

I haven't taken either of these in quite some time, but I have just recently increased my fiber/fluid intake by quite a bit as an on-going quest to keep myself naturally balanced. Normally I don't have any problems with this, but I think due to the fact that I've been getting a ton of exercise and drinking more water than usual... now I'm on the opposite end of the spectrum!

I'm fairly certain I have Irritable Bowel Syndrome or Crohn's Disease, as both constipation and diarrhea are not unusual for me. In the past 12 hours I have had semi-normal stool and now it's completely liquid. I'm having a lot of rumbling and uncomfortable movements (nothing painful or bloody so far though).

The fact that it's completely liquid and keeps coming is rather upsetting. It's a nice change of pace, but then again it's also a condition as well. I took 1 loperamide pill in hopes to solidify things a little, and I will lay off the fiber (Raisin bran lol) for the time being.

Does this sound like the right course of action? Can anything go wrong here? I just want to get things back to normal. Any advice on how to maintain with IBS is appreciated.

Also, what are some safer ways to treat sudden diarrhea like this? Any home remedies? Something that's gentle on the system is preferred.

Thanks
