hydromorphone and alcohol

[norcolepsy]

Swim is wondering when it is safe to drink alcohol after a (non time-release, oral) 4 mg dose of hydromorphone. Swim doesn't regularly drink alcohol, but tonight will be a special occasion. Swim may be drinking semi-heavily so he wants to make completely sure that he's not putting himself at harm. Swim was thinking 4-6 hours, as that is how long many descriptions of hydromorphone list the duration. However, swim often feels the subtle effects of a hydromorphone up to 12-15 hours after a dose. Swim's not even sure how bad it is in the first place to mix alcohol with the opiate (as there is no filler, *i think*), but would like for some of the seasoned experts to donate their 2 cents.

Thanks,
