I have read several articles that indicate that after a period of abstinence, the brain not only heals but also regenerates.

Personally, I have no doubt that my cognitive abilities have improved after abstinence. Complex tasks at work are far easier, and I can focus better.
Coordination improves. I do several tasks as a technician requiring a fair amount of dexterity, much easier.
Also, yu'll find yer spellung wll improov.
Good news, all around
Keep well
