I have a similar problem, not quite the same though...I've been trying since oct. of last year to get it on the "same time, every day" plan...not having that much luck. I was doing martial arts alot before the summer started and I had things under control...cycling seems to cause stranger things though (although I haven't been cycling much last 2 years and now boom I'm doing 80Km rides to start).

I'll keep an eye on this thread and post any insite I have.

BTW Imodium SCREWED ME UP BAD, if your going to use that don't abuse it...I relied on it to get me through exams and some important times in school and I err well I had to use castor oil...and I thought I was going to die...I've felt better wiping out on my mtn bike and pouring my blood on the ground.

Anyway it's nice to see people aren't to shy to discuss this stuff
