@becsbuddy. Thanks for the wisdom. The reason I want to take hydrocodone before the cystoscopy is as stated before. I understand your point though. As lay people it seems to be OK to take the hydrocodone but the medical staff needs to be aware. I did send a portal message asking about sedation, etc. The reply was they will use a numbing jelly and that's it. She said the whole thing goes so quickly that it will be OK. We'll see... Two more days to wait. Thanks for everyone's input.
