Tell me more about acetylcisteine. How much per day? Is there a theory behind that use? Etc...
I take at least 2g per day. Some NAC supplements have some selenium and molybdenum included, so in those cases it's important to be mindful of not taking too much of those trace minerals.

The effect is not dramatic like a stimulant. It's more like it makes my attention stickier, and allows me to hook into long problems more easily. It doesn't "feel" like anything, just causes a noticeable change in what I find engaging. One weird effect it has had is I completely stopped craving alcohol, news and social media. I usually spend hours on Reddit when I don't have anything on my plate. I'm talking 40k+ karma, multiple posts/comments per day type of addiction. I see multi-day, multi-week gaps between comments on my account now, which is unheard of for me. I know it's a silly heuristic, but it's an example of the behavior change.
I've seen much smarter people than me on Reddit say that effects may take 2-3 days. The supplement itself is pretty cheap, and negative side effects are minimal to non-existent. I am seriously astonished that such a common and accessible supplement has had the impact it has had on me. I personally think the cost/benefit ratio is so good that warranted skepticism can be overcome with a self-experiment.
If it doesn't have an effect, then at least a person can check off the "glutamate-glutamine system" checkbox in their quest to address executive function problems.
