Has anyone else experienced this?

Yes, I posted the same question a few days ago b/c I hadn't seen anyone mention it either and a few people responded with a yes. Mine was horrible, very sudden and severe but only lasted one day. I'm on day 6 now and it happened on day 2 or 3 but none since. Hope yours clears up quickly too. One thing I wondered - the first 2 days I'd had a serving of sugar-free pudding (allowed on my plan) and the prepared ones have sugar alcohols in them. That might be the cause for me, as I haven't been brave enough to try it again! I don't think the ones you make yourself have those.

I'm on a clear liquid diet, so no pudding or anything you cant see through. I'm starving lol

Oh yes I had it the whole time.

OMG I would KILL to be any of you. I've been plugged up since Saturday (my butt and I had a rather significant disagreement Saturday, for about 2 hours, I was laughing the whole time) I need to go, and significantly in the next 26 hours or there is a chance I will not have lost enough additional weight on the pre-operative diet and they may cancel my surgery.

Laxative??

Suppository? Enema? (Sorry, rather personal but I have chronic constipation so I know of these things)
