I wasn't really worried about heavy DT's, I was able to not drink for a couple of days without bad physical side effects before I stopped for good. I experienced a mild hand tremor, but no seizures or anything like that. And yes, I was drinking mostly beer at the end, though I'd spent plenty of time drinking red wine and rum beforehand.
As far as I know you have to dig yourself in pretty deep, generally, to get heavy physical withdrawals. For the vast majority of people alcohol addiction is 95% psychological.
