Oh Angel...I'm so sorry to hear that you're feeling so bad!! I know what it feels like to have tried everything and nothing seems to work...
It sounds like you're on the right track though...it just may take a little patience and persistence before you see some improvement.
How long have you been on Dicetel?? I took it for about a month and it did nothing to help me. I've just started another antispasmodic called Modulon (and I'm crossing my fingers hoping that it'll work)...I've been on it for 2 days now and this morning my stomach was a little grumbly and after I took it...no more grumble...so maybe that's a good sign that it might be working!!
Hang in there....even though it seems impossible right now...this too shall pass....
Have you thought about getting the hypno tapes?? I hear they're really awesome and have helped lots of people.
