What you describe above sounds like a pretty extreme case of physical dependence to me. Keep in mind too that you could easily experience much more severe symptoms this time even if you never have before..and even when you are still tapering. The HAMS method promotes controlled drinking which is not a topic of discussion allowed here.
Please be safe, you cannot reason your way out of withdrawals...and they can be very dangerous as has been stated multiple time here. And as also has been said, we cannot advise you on a taper program as that would constitute medical advice. Please seek some if you feel you need it.
