Yeah, I get the back-and-forth between D and C thing too. Sometimes the C will go on for three or four days, accompanied by the MOST painful bloating that makes my stomach swell up two pants sizes...only to be followed by D for a week and I wind up dehydrated and my clothes are falling off my butt. It's like...it's not bad enough that I have to feel like crap all the time, but is it REALLY necessary that my clothing NEVER fits because of it??? Rarr!! I have to keep different sizes of pants and I almost always buy clothes that are a size or two too big just in case I'm trapped somewhere and my stomach decides to go Willy Wonka on me.
I've done all kinds of crazy food plans to try and help, but nothing is 100% right. At best I get 75% relief, but stress is the #1 killer of a happy tummy in my world, and whose life doesn't involve stress? The only time I got even close to feeling normal again was when I was working for my Mom and being taken care of by my family. They stood between me and the Real World - but you can't LIVE like that. That's just surviving, and I want to LIVE.
