Sorry to hear you drank Eve, and unfortunately, withdrawals do get progressively worse/longer each time for many people - it's sometimes referred to as "kindling". And you are right to think that taking a drink now would be the last thing you't want to do - because it definitely wont be one - and the withdrawals will start all over again, likely even worse than they are now. And for some of us it only takes one time - 2 bottles of wine at once is a pretty extreme amount, so yes - even drinking that one time can make things as bad as they are.
The flip side is that withdrawals are always finite - and they always improve over time. I don't know if you've seen a doctor or not but it's never a bad idea to at least get a checkup when you stop drinking to see if anything else needs attention. Many of us neglect our diet and exercise needs when we are drinking too - so it's kind of a double whammy. Eating well, drinking lots of water, avoiding affiance and sugar can all help ease the symptoms - but again please to see a doc if you think things are too bad.
