The only things I'd agree with are soluble fibre is good and a clonoscopy is neccessary to check for IBDs. If it wasn't for the wait, I'd say get another doc before you have the colonoscopy! You shouldn't feel a thing during the procedure and only have some gas problems afterwards (a bit sore but it goes), so I'd worry about any doc who says people always have pain - sounds like he's doing somehting wrong! The idiot!!!! The prep is pretty horrible, but read Jill Sklar's notes on it and you'll be fine - being ready is the key (I wasn't! ).
Chin up chuck! We'll get ya through this. Wish you could fly over here and see my doc. He's a darling!
