I don't really know the ins and outs of alcoholism, so I'm sorry if this is wrong. But you said it was a small bottle of vodka? So, if you've spent the last six months wasted, does this mean a small bottle won't make you drunk - just slightly tipsy? If that's the case then that's got to be good - that you weren't totally steaming drunk, that yes okay you had a drink, but there's definitely a difference in having a drink and being far too drunk.

I know this doesn't apply in all situations, I know some people have to be teetotal to stay in control. But, if all you've had is a naggin of vodka so far, and are feeling discontented about that and have therapy tomorrow to motivate you to not get drunk, then don't catastrophize it. You can get support at therapy - don't cancel!!

I say that as someone who got drunk to the point of oblivion at the weekend. I drink socially, but about three times a year get over excited and go too far and have a disastrous night
