Got too high and now I'm anxious about trying again

Hey guys and gals,

Been experimenting a bit different delivery methods recently, started out with tinctures of Sativa nd indica, trying to find out what works best. Bought a disposal vape pen that is 50/50 CBD/thc that I tried a few times with very limited results.

Well... About a week ago I took a massive drag, coughed for about 3 min and then proceeded to have the craziest high ever. It was as if I was lagging, everything was choppy and low framerate, for lack of a better term. I had derealization and some really weird tangential thinking. I am rather proud of myself as my wife didn't notice any difference (I was trying reaaaally hard to act normal). Ended up sleeping it off but had some hangover symptoms for most of the next day.

So I'd like to go back to trying but I'll admit I'm a bit nervous about getting that way again. it's either a very very minor effect or tripping balls. Can't figure out how to dial it in for a middle ground.
