Some people take things differently. Some folks are pleasantly couchlocked for an evening at 5g and re-evaluating life at 10g, and some are fine with 30+g and going hunting in the swamps on a full moon.

I'd suggest you try ~12g next; with knowledge it might be a bit too much but some comfort you know what itll be generally from the smaller doses. if thats not what you're after, then maybe steps at 18 and 24g.

Do pay attention to frequency warnings and such commonly cited; too much too often is a waste of good shroom. Also consider extracts, I personally found the larger doses hard on the stomach, even powdered, compressed, and rendered easy to swallow with honey. Vodka is a great solvent and can be evaporated back off.
