Keep that in mind next time you drink.
That said, there are drugs to make it easier. Im not sure how the system works in the uk, but if its like the us, if you go to a hospital, they can offer meds that help you through the process, lettung you quit cold Turkey without having to taper, and without feeling like **** the whole way. Even if you dont eant to stick around through rehab, 2-3 days of detox in a controlled environment, where you don't havr to worry about any withdrawals killing you, imo is much better than spending a week tapering down and being in hell the whole time.
