I doubt it, if your only drinking 1 beer a night. One beer isn't usually enough to really feel much off of. At least, I don't feel anything after one. Maybe very slightly after two, but I never really feel it much after one beer unless it's 8-10%+. Of course, if you truly do need that one beer to get to sleep, then I don't know? However, alcoholics usually drink at least several a night and they need it.
