I take 2.5 grams, then like thirty minutes later top it off with another .5, and I ain't gonna lie, I religiously use it on weekends, and top it off with a bit of booze.
It doesn't send me over the top.
At one point I noted dosing too much at once would make my hear beat too fast, sometimes issue comes up with my dosing regulations, but I find that keeping it a 3 grams and nothing more works fine. Spacing out that last topping of .5, also seems to help from me being overwhelmed. Also utilize beta blockers to combat these kinda issues.
I guess you can call it manic to a degree, it isn't like a coked out mania, but the feel good, confidence booster, I need. For some, they call that reality normal, coming from my low points, may be considered manic, I call it functional.
Keep in mind, I use it, never abuse it, only twice a week. If the weather doesn't allow, plans fall through, and I can not utilize the drug for practical reason, I pass on using it.
