HI mankymummy and welcome to the thread.
I suppose it depends on how you drink, etc, but...
Try to identify trigger times- what time do you usually start drinking?
Plan things to do as well- keep busy, keep active. Write down all the reasons you want to ease up on your drinking, and try to be honest with yourself- how much is alcohol impacting on your life etc.
Depending at what level your drinking is at, be aware of withdrawals, also that you may find your sleep is affected initially, but these pass.
Obviously, if you are drinking a bottle of spirits daily, I wouldn't suggest stopping outright!
If you are really worried about the level of your drinking, you could go to your GP, local alcohol service etc. for advice and info, and there's AA too.
Thing is, I don't know your drinking history, so sorry if i'm way off the mark with any of this!
I suppose keeping busy, planning your time, things like that, are really important to help break something thats become a habit, Hope this is helpful.
How did you do the other night? Are you wanting to try and cut down a bit or stop completely?
Have a read back over this thread- there are posters who want to cut down, and also ones like me, who have stopped completely, so there will probably be something you find useful somewhere!
