Waiting Period for Drinking Alcohol After Accutane?

I know that drinking alcohol on Accutane is bad, and I when I was on it I noticed it made me feel sick just having a few sips of alcohol. I've been off of it for 4 days and I'm still not able to drink without feeling sick from a small amount of alcohol. Is this a permanent side effect? How long should I wait before I can drink alcohol again?
