Heart racing with alcohol

Hi all, i’m looking to see if anyone has had this experience. About 5 or 6 months ago, I noticed that every time I had alcohol around night time and went to bed, every time I woke up in the middle of the night my heart would be racing. It would be very noticeable & it would be every time I woke out of my sleep or went to pee but i’d be fine in the morning. I decided to stop drinking for a bit after thanksgiving because I got crunk that night off wine & ended up having a panic attack at about 3am that truly felt like the end. Since then, i’ve been dealing with mental issues & decided drinking would hinder my progress but a couple weeks ago, I had 2 glasses of wine for the first time since thanksgiving & I had the same thing happen. not the panic attacks, but the heart racing when I woke up in the middle of the night. i’m not currently on any medication, I was dealing with pretty bad health anxiety and cardio phobia that have gotten so much better but I still have the underlying “what if” about my heart. I just recently started getting back into exercising too, I told myself I wouldn’t drink until I got into shape, I thought maybe being so unfit was causing the problem but idk. I know people say panic attacks and anxiety can’t kill you but I think they really did end up affecting my heart. I’m seeing a cardiologist & did a halter monitor for palpitations, but I just wanted to see if anyone else has dealt with this. and if so how is it now? what was the cause? and what I should do. I now fear drinking & I would like to still do it in occasion, but i’m scared that i’m gonna go into AFib & die in the middle of the night.
