My problem with Moda/Armoda is that I feel like a tweaker when I'm on it, and I only take enough to get an effect. I get sweaty, physically stressed, and just generally feel like I'm taking something that is not in my body's best interests. I have to drink liters of water to avoid a headache. I also have noticed some of the dopamine effects(increased risk taking and addictive behaviors). I'm slightly bipolar though(type II, pretty mild) so maybe it's just not for people like me.

It does work pretty well for focus though, and is really nice for my middle-aged brain which often is tired throughout the day.
