Helpp!!

I often drink at night just to chill after work once my family has gone to bed. Most people find that completely acceptable, but for some reason I always feel guilty. Not sure why that is and I would love some input. I like to drink, my partner knows I drink and we haven’t had any problems with it, but somehow Im always feeling morally wrong I guess? How do I fix this? Anyone else feel this way or do I just have anxiety?
