Hell yeah! I regularly use creatine, spirulina, and I juice a lot. It helps with acuity but I also work out, so the creatine has the double advantage of helping me with it, as well as from a cognitive standpoint. As of late, actually... I was kinda slow, given recent events... I know it's taboo, but I've been using Modafinil which I got from the internet (https://drmodafinil.com/) because my grandpa had a prescription for Provigil lying in the house and I figured that just in case it arrives and I get asked about it, I show it. Didn't happen, but I don't recommend that you use it too often because it loses its magic and I don't think it's really healthy in the long-term.

I find Modafinil to be by far the most effective. It really gets my attention in 10 places and definitely helps with decision making.

That's true. Safer payments also.
