Yeah I just stayed off the acitretin for the day before and the day after, took a little e less than I normally do (2.5 pills total- 1.5 then another 1 2hrs later), and I was fine. No unusual side effects, just the usual dry/painful mouth from the gurning the next day, and the tiredness.
I should say I'm on a relatively low dose of acitretin, 20mg/day. I took (ro)accutane when I was younger and the side effects were much worse.
The doctor says the acitretin may be pushing my cholesterol up, so bear in mind, it does have an effect on your liver. Try and stay off the booze (I had about 2 pints all night which was probably 2 more than I should have), test your gear if you can (check pillreports.com if you can't), let someone know what you're on and what prescription you're taking and don't overdo it.
