Oh, absolutely. But I don't drink anymore. And I'm definitely not talking about recreational use or combining things!

Rephrasing my question:

Since I've discovered that alcohol and being around marijuana (I don't smoke) affect me in unpleasant ways, and since this seems to be universal among those with PCS, I'm wondering if people have found that actually medicinally necessary substances that are similarly psychoactive, such as surgical anesthesia or narcotic pain medicine, are similarly challenging to a brain that's compromised. I've been putting off having elective surgery to repair my eardrum, as I'm worried about both the anesthesia and about having to take some sort of narcotic for a few days. Also, I have back pain that comes and goes, and being able to take the occasional vicodin when it's severe wouldn't be the worst thing ever, but I've avoided the stuff as I'm not sure how it will react with my brain.
