How long till physical addiction

I’ve been a major drug addict my entire life but never enjoyed alcohol it always made me feel shitty for not a very good buzz. But I’ve recently started drinking more and more and I’ve noticed hey it doesn’t make me feel as sick the more I’ve been drinking regularly.

I do this about 3 days in a row then skip a day or two pick it back up and since I already come from a history of addiction I know I’m heading down a path I’ve already been down and should stop just wondering if I keep it up to a pint a day how long till I’m having dts
