I haven't I haven't taken those two together. Did you ring the medical line, or ask your pharmacist as they often have a better idea about how medications interact then Doctors? Does it talk about that reaction on the side effects list?

It could be a tummy bug or something else causing the reaction, so it might just be a coincidence. If your Pharmacist doesn't think it would be the two together, I wouldn't give up on the Diazepam yet in case it was a fluke, because if you found something that works it would suck if you had to stop using it.

Hope it works out and someone is of more help then me?
