ledkr, sounds like how I was when my two were younger. DS2 was a nightmare baby and I used to be desperate for a glass of wine during the evening when he was whingeing till bedtime. Now they are older and DS2 is not so bad and DH and I have gone from having a glass or two most weeknights and more at weekends, to having nothing during the week.
Only problem is, it's been creeping up again. It starts if we have a couple of leftover bottles from a party or whatever - we don't seem to be able to leave it there till the weekend. Then I'll get a taste for it and the next time I'm in the supermarket I'll pick up a couple more bottles. Then if it's there in the house I will be tempted to crack one open, even if DH is working away. I don't even "need" it to ease the stress of DS2 anymore like we used to because he's older and much easier. But for me, it's the habit of liking a glass with my meal of an evening that's become the problem. And then because there's some left in the bottle, I'll pour another half glass while I'm sitting with the kids relaxing after tea. And I'll finish the bottle the next night because I don't want it to "go off" LOL!
I don't think the amount I could drink during the week would be a problem as such, it's just that the waking up with a headache and feeling out of sorts for the first couple of hours of the day seems to affect me more the older I get.
DH is pretty stubborn and if his solution is just to say to himself "Right - no drinking during the week for me". Which works for him, but then he drinks a lot at the weekend and so undoes his good work!
I think the answer for me is just to not buy any wine during the week AT ALL. If it's not in the house then I can't drink it. I also then really enjoy and appreciate my couple of glasses on a Friday and Saturday night, probably much more than if I'd drunk most week nights. Seems to work for me......until the next party or Christmas or whatever and then it creeps up during the week again.
Sorry.....that was a bit waffly really....
