Same here, especially bad if insufflated.
Trust me when I say that putting at least 6 weeks in between rolls will maintain the "magic" sorts of feelings, if you roll to frequently MDMA just becomes shitty meth that lasts no time at all and leaves you somehow even more drained than meth would. 2C-B however can be used daily, there is mild concern over its 5HT2b agonism potentially causing valvulopathy if it's taken daily over a period of years though. I used to do 6-8 week binges of daily 2C-B use, my fiance and I often housing a gram or more over that period. There was a good amount of miprocin, DOM, LSD, MDA, MDMA, 3-MeO-PCP, and THC concentrates in the mix too. The main reason we'd take breaks from 2C-B was because another psychedelic would create tolerance that dulled the 2C-B, and we didn't want to waste it. Also the nasal damage was adding up so we started taking more doses orally.
This was during covid in a rather dense city in Maine, over a frigid winter where I was watching a lot of homeless people freeze to death despite there being entire apartment complexes empty bc they're kept as "investment properties". It was a really difficult time in my life emotionally, and using 2C-B often helped me to get through that to a point of compassion instead of hatred, if that makes sense. I still harbor hatred for the greedy bastards who would rather let somebody freeze to death on the sidewalk outside my apartment than let them stay in a room in their "investment properties", but I'm much less likely to unironically chase the property manager out of the apartment leaving her crying and shaking and shit after those periods of 2C-B use.
