mrsmvc I know how you feel. I was drinking for much longer than a couple of years though. However, during the past 18 months I had managed to drink a bottle of wine each night, and sometimes even a bottle and a half and still function.
I gave up this pattern of drinking around 7 weeks ago (so early days for me). I had a liver function test and was expecting the worst. I was extremely surprised to find that my ALT's and AST's were very low and well within the normal ranges. This is probably going to sound very stupid, but I am extremely grateful that I had these tests done, as it made me realise how serious this could all be if I continued with my previous behaviour. It was the catalyst to changing my mindset towards alcohol.
I am waffling now, but i guess what I am trying to say is that it is different for everyone, but the LFT's were a real crossroads for me. I can honestly say that since I have stopped drinking at home I feel better in the mornings, I sleep better, I actually have a better evening, it is way more relaxing.
I have been out and had a few social drinks, and was worried that it would spark a craving for drinks at home. This hasn't happened, but I am conscious that it is an easy thing to slip back into.
