I can't just think "I won't drink today" because that would do my head in, not knowing about tomorrow or the day after. I'm a worrier, and like to have everything planned
I can't commit to forever it just freaks me out
Joey you can't have it both ways, either you commit to forever or you are stuck making that decision, day in day out, for the rest of your life. You sound very confused at the moment about what you want and it's stressing you out!
If you think you want to stop drinking, the idea is that you just stop one day at a time. You don't have to think of it as 'forever', you just think of it as 'not now'. Do you think you would benefit from gong to AA because they will be able to explain this to you much better than I can.
Chasing the best thing you can do about your holiday is plan, plan plan. Don't leave it to chance or you will most probably drink and much more than you really want to.
If you decide to not drink, renew that decision each day, just like you do at home and use all your strategies to avoid picking up. Instead you can enjoy lots of tropical fruit juices, etc and have a happy, healthy holiday.
If you want to drink, plan strategies to cope with that too. For example, if you have one or two at lunch maybe go for a siesta, then get up, have a shower and be ready for the evening, rather than drinking all day.
There are lots of choices you could make, you are the only one who can really decide that but whatever you choose, plan it carefully, just like you do every day at home.
And if it all goes wrong and you do drink one day that does not mean you have to carry on. You can stop any time and go back to soft drinks. We will all be there with you in spirit, have a fab time x
