My OH and I gave up together at the same time. Prior to that we spent many a 'happy' evening drinking copious amounts of red wine, talking absolute bollocks, and smoking and smoking and smoking - until the wee hours of the morning. The next day was a bit horrendous but we always had a chuckle about the daft conversations from the night before.
That has all changed now - and it's probably not a bad thing. I've cut back on drinking BIG time and OH has given up drinking completely now. Over the last few months, since he has given up smoking - my OH has started to get incredibly angry when he's had a few - and I mean maybe 2 or 3 glasses of wine or a couple of beers - not much. And it gets worse the more he drinks. It is seriously a Jekyll and Hyde moment - he is normally the most laid back, silly thing around - but give him a drink without a cigarette and you had better start running. He is never violent I hasten to add - just really lets you know what he things of you right then and it's not very pleasant!
So in order to save our marriage, his dignity and a night a police cell (he got angry with a policeman just recently :eek - he has given up drinking entirely. I'm not - I'm still okay with drinking but it is quite interesting the effect that smoking had on him.
Gosh - I feel like we have finally grown up into mature adults now - and it's not a bad place to be....
