Decided to try Antihistamine after extensive research. Started with a low dose as I always do with new compounds.
T+0:00 - Took the dose with a light meal. Sitter present and informed about expected effects.
T+0:30 - First alerts. Subtle shift in headspace, slight body sensations.
T+1:00 - Effects developing. I noted each change carefully. Took a moderate approach to exploring the headspace, not pushing anything.
T+2:00 - What I'd consider peak effects for this dose. The experience was milder than expected based on reports, which is fine — I'd rather undershoot than overshoot with an unfamiliar substance.
T+4:00 - Effects subsiding. Made detailed notes about the experience.
Overall: Interesting but not overwhelming at this dose. Gained a good baseline understanding of how Antihistamine affects me personally. Would consider a moderate dose in the future now that I know my sensitivity level.
My protocol for any new substance: allergy test first, then low dose, always with a sitter, always with research completed beforehand. Patience is the most important harm reduction tool.
