Should I restart drinking?

Hi, I stopped drinking alcohol 2 months ago and even though I feel better and freer from the addictions I have noticed decrease in productivity and dramatically less willing to work especially on repetitive tasks.

I am self-employed and can’t afford low productivity for too long.

My alcohol consumption was around 6-7 UK units a week.

I was wondering if any of you tried the same and experienced the same and if this is just withdrawal symptoms that eventually go past?
