Well that's your answer, isn't it? Take it off the table for now so you can relax again.
Good for you for having the self-knowledge and insight. and WELL DONE for not having anything last night! ⚘⚘⚘
Therapists give advice and if he doesn't have expertise in alcohol treatment then I'd take everything he says with a pinch of salt. You can always just tell him you don't want to reintroduce alcohol.
Few people really understood my issues with booze as from the outside I generally didn't drink much and I was very disciplined. When I got too pissed at parties most people shrugged it off. What they didn't see and even my therapist who is awesome and I have seen for 4+ years didn't see was how anxious the whole thing made me. How I had that constant internal battle you're describing - do I drink tonight? If so how much? Will I be able to stop? It is so exhausting!
I've found the Stop Drinking thread on reddit really helpful. Although pretty much everyone on there says you can't go back to drinking "normally" after a long period of abstinence.
What I'm starting to wonder is if it is worth it. I love a g&t but is the brief pleasure worth the anxiety around having a bottle of gin in the house? What if I drink every day after that? What if I don't have control?
The clincher for me was pushing it to extremes - if you could be always drunk or always sober which is better? Sober. Every time. No one is ever "too" sober 😂😂😂.
If you need booze to make something fun it's probably just not very fun and you can stop doing it / leave.
You are doing really well. Keep it up!
