Can you still drink alcohol and/or smoke weed?

I’ve only been symptomatic for 2 months after getting covid so I still don’t have a diagnosis, but I haven’t been able to smoke weed at all because it raises my heart rate and last time I drank alcohol I got sick (I’m taking metoprolol so could have something to do with it). I used to smoke weed often and I wanna be able to drink again too, but I feel like it makes me sick. I’m 22 and just wanna be able to have fun. Do I have to avoid it forever?
