Taking a strong stim and trying to "mellow out" using another stim is not wise I'd your wanting to just amp the hell out and go full tweaker mode, then fuck yeah double down and peak it the window in your covers with a .45 because "Theyre onto you" I've been there plenty of times, it's a thing.
But personally I'm getting to old to be doing all that.
Now if you want to chill out a bit, some benzos will take the edge off, a beer wont cut it, downers will definitely calm the nerves, pcps big no no. Best thing you can do is put the stuff down so you can enjoy it later, i mean why waste it all in a short time? You spent good money on it most likely?
Take your time enjoy it, let it be something you do for fun not something you need to exist,
And if you feel you need something else to calm down from something that was supposed to bring you joy all your doing is putting yourself in a loop of frustration. Take it from someone who has to figure this out through trial and error. Or don't you always have options, this is just my 2 cents.
