What are the effects if you were to drink alcohol while taking campral?

Nothing. If you drink alcohol when you take campral, you do not have side effects. It's not like Antabuse (disulfiram) [you feel sick if you drink and take Antabuse (disulfiram) at the same time]. Campral helps you when you are withdrawing from alcohol: feeling anxious, trouble sleeping, sweating. What kind of support do you have? Congrats on making important changes in your life!
None. Campral has practically no interaction with alcohol; but to drink intake Campral reflects somebody who does not want to get off of alcohol.
