Similar for me. No idea of the gram dosage but... a lot. Effect lasted about 6 months, then tapered off slowly.
Repeated again roughly yearly. After 4 difficult and unpleasant trips I'm fine. Never reached the sense of utter well-being I have for the few months after a trip but I'm fine.
I will say that drinking any alcohol basically negates the positive effects for me for a while. As in, I'll have a cocktail and then won't feel "right" again for a month or so.
