Unable to drink alcohol anymore?

Been drinking for two years, a binge drinker for around one maybe. Months ago I was typically having basically a four lokos a night.

However a couple months ago I noticed that I just stopped getting the buzz I used to get. I assume this is tolerance but I didn’t know it’d be this severe. I also noticed I would start to get a little more nausea than normal. This caused me to take a roughly two month break as alcohol started being less fun.

I recently started again and I drink every few days roughly. I thought the long break would ease up my tolerance a bit however I still don’t really feel a difference. Only this time I wake up very nauseous and end up vomiting. This didn’t used to happen, I would only wake up very thirsty with a headache.

Perhaps it could be my change in diet, as I eat less than I used to before going to bed. Or maybe the long break and it’s my stomach readjusting? I just want to be able to drink again. This sucks. Any ideas?
