PAWS - sense of humour and memory loss

[Nemochaken]

Hi, guys!
Anyone can help with the question that is bothering me.
After quitting weed i have a problem - my perfect sense of humour became a total utter sh**.
Somebody who have survived paws or is on some stage of restoration, will it become better over time?

Also im struggling with memory loss. When i was on weed, i consistently lost keys, glasses and so on. I had problems with short memory. Now after quitting i have no such problems anymore, but my long memory is working very bad. I can remember things about some years of my life (stories, etc) that i actually remembered when i was on weed. Will my memory also improve? or it is know irreversible?
