hi! - having a really quiet evening all on my lonesome!, i dont mind tbh, i need a bit of thinking space every now and again!
prof!, really nice to meet you!, bloody well done on your 5 days, what an amazing start!, i know only too well what a fucking hard job it is at times! - as to when you will start feeling better, i can only go on my own experience, i definatly felt better after about 2 weeks, my mood lifted and i slept better, a proper restful sleep, not a booze induced coma! - i find that the longer i stay sober the easier it becomes, im very aware that drinking is not my main thought of the day, its becoming almost an aside - TODAY I WILL NOT BE DRINKING - its my first decision of the day, a quick, fleeting thought, then i just kind of get on with life, dont get me wrong, i still have the occasional almost overwhelming urge to drink and drink till im wasted, i do find the fight is becoming easier now though - i have my strategies in place, do the drill, call a friend, tell my dh, whatever i do though, by the time i have run the bath, or dialled the friends number etc the urge has passed and im back on an even keel!
as to health, i was shocked at first at how well i felt so quickly, if anything, that feeling has grown, i think i feel as well now as i ever could, mainly due to the fact that i have such peace in my head, the mental wellbeing i feel is only adding to the overall sense of phyisical wellbeing iyswim? - i cannot put a price on the feeling of calm and serenity i feel every single day (my friends think its hysterical that i feel 'serene' as im well known for being the exact opposite), my zest for life is increasing daily, i wish i could bottle all this positivity and send you some! 
not drinking as not made life a bed of roses, i still have all the usual crap to deal with (quite a lot right now!), but not drinking has enabled me to be the best person i can be, i can try and make things right, and do it in the knowledge that im actually being effective, not wreaking havoc where ever i go - thats a very nice feeling!
