I cannot say what 'to do', but I can say what not to do. Never stop meds suddenly.
When I first came here years ago, I was on a very strong dosage of Gabapentin and Vicodin and one very strong vodka/kalhua/milk drink at night. After a while, I stopped the alcohol completely. About 8 months or so later I weaned from the Vicodin over a few weeks until that was done. I stayed with Gabapentin for quite a while, but s l o w l y took it down, then paused for awhile, then did it again. Since it was such a high dosage, this process took some time. When I fully stopped, even after weaning so carefully, it was a month of severe withdrawals and near-violent restless leg (which I had never had before). When that finally passed .... I was 'drug' free.
Being patient is very important.
And ... welcome to the Forum ^_^ You'll find many very knowledgeable and kind people here.
