personally i think u should be ok as long as the codeine dose wasnt too high, not sure how things r stateside with cough meds!? hope it aint set u back m8, if so keep in there as its the rest of your life that u gotta weigh it up against. im sure you'll be fine, plenty of fluids (as i have mentioned tonic water) multi vits, hot baths,lavender & maybe a short dose of sleepers just to get through the madness of insomnia (my doc gave me 7 days of temazepam 10mls to help - they r really cutting back on benzo scripts this side o the pond)

hope all is well

keep on keepin on

good luck
