Hello guys! Sorry to post, which may be an irritating question but I have a lot of trouble finding an answer to my specific scenario.

I drank pretty heavily, 4-5 time a week for about 6 months.

Well I realized this isn't quite a phase but rather the beginning of alcoholism. Drinking due to stress, drinking rather than dealing with the hangover. Drunk at work was the last straw. I quit. It's been fine. Have thoughts about drinking but they're relatively easy to push away.

Anyway, I had COVID last month and cannot tell if my reoccurring mild cold symptoms are from stopping alcohol or lingering long COVID.

Anything insight would be greatly appreciated.
