Hi AlaskaGirl,
Gneiss totally nailed it as to the reason I felt you should see a doctor for detox. It isn't only the AMOUNT of alcohol you ingest, it is your response to it. Drinking to the point of blackout means a LOT of alcohol for some, but less for others. Either way, it is a sign that toxicity has been reached.
Do be careful. And do something now. You are wise to listen to the people here who have nothing to gain or lose by telling you like it is.
Keep up posted on your progress!
