IDRA-21 effects lasting 48-72h, anyone else find that persistence kinda unnerving

Been reading up on IDRA-21 and the AMPA positive allosteric modulation angle interests me. The thing that catches my attention is the persistence. Half-life is listed at 8-12 hours but effects supposedly last 48-72 hours after a single dose. That's a big gap. Means the downstream LTP effects keep going well after the compound itself is mostly cleared.

I tried 10mg once, just to see. Felt a mild clarity the next day, like words came a little easier when I was writing. Could absolutely be placebo. Day two was less noticeable. No headache, no overstimulation. But I was honestly a little wary of the excitotoxicity risk so I stopped there.

The dosing schedule people talk about, 10-30mg two or three times a week, seems reasonable given that long tail. But I keep wondering about accumulation. If effects persist 72 hours and you dose every other day, are you constantly stacking on top of residual AMPA modulation? Imo that's where overstimulation and the theoretical seizure risk actually become worth thinking about.

Anyone running this regularly and tracking how they feel across the week? Especially curious if anyone noticed a tipping point where it went from helpful to too much.
