Weed affects different people in different ways, if you feel that it's stopping your memory function then you are probably right to give it a rest.

Personally I'm lucky I guess, I don't suffer from this. Somtimes I forget for a second what i'm in the middle of ~ but ONLY when I'm high and only for the first hour or so.

I have been an everyday smoker now for over 10 years with odd breaks here and there for holidays etc
