A confession...
I bought everything everyone had suggested, dry mouth spray, wet wipes, ear plugs etc etc...didn't use anything!
Dry mouth thing made me sick the two times I used it, i got the wax ear plugs and they were so strange I couldn't get on with them, i was so grateful to have a shower on the sunday, though, and don't be at all surprised if they catheterise you - I asked and they said they might, they might not, but when i came round I was.
