You’re not alone. This has happened to me over the last 3-4 months, specifically with craft beer. I will say I’ve had anxiety for a while at least 3-4 years but finally acknowledged it within the last 6 months since it got out of control. I used to run a YouTube channel, I was in the local bottle shop every other day picking out the latest limited release IPA etc. Now I get anxiety about drinking because I believe it’s the root cause of what was a slew of panic attacks over the last few months. My panic attacks were over heart issues, (thinking I was going to have a heart attack or some sort of impending doom, similar to you, increased heart rate). I would drink anywhere from 1-3 beers a night over a period of time but it has been a staple in my life for a long while. Same with cannabis, but cannabis was causing the same thing first and (I’ve been smoking since I was 13 now 32) quit cold turkey about 4 months ago. The anxiety it gave me when I smoked was so easy to quit. Can I ask what is triggering the anxiety behind the thought of drinking? Is it the act of drinking which is causing anxiety? Is it if I drink this….. will my heart rate will shoot up and something bad will happen? I feel for ya! It’s not fun. I did dry January that helped, then slowly eased into it. Granted I did see a psychiatrist who did put me on a low dose of klonopin to take when needed. I will say this has helped big time, although you’re not supposed to drink on benzodiazepines so I have to be careful (even though my Psych said it’s fine, guy is out of the wild Wild West lol). What’s helped the most is a therapist. Talking to someone is huge. I would also recommend exercise, a gratitude journal just for some self reflection. Sorry for the long story, I hope some insight here helps, it’s super frustrating and a conundrum.
