I’m not any kind of weed expert, so take this for what it’s worth…
If I had to guess about why you felt “not normal” for a whole day after your two hits, is because your tolerance to THC is nonexistent, so you’re feeling every bit of it. And also I’d guess that, since (IIRC) you don’t drink, you’re more sensitive than a lot of pot smokers to variations in how your body and mind feel.
I think what strategy you should try next time depends on what you are trying to achieve. This also relates to your question about whether or not weed is “for you.”
From reading your post from yesterday, it seems like you were after something that would help you sleep. How I interpret what you’ve reported is that it didn’t help you sleep as much as you had hoped, and you also felt off the next day, with brain fog and some body effects that you didn’t like (?).
If that’s the case, then yeah, something with a lower THC percentage, and/or some CBD in there might help you dose yourself with a smaller amount of THC. That might give you the effect you want with less unwanted effects. (You could also try that pre-roll again but just hit it one time and see what happens.)
You should be able to find strains that are around 1:1 CBD:THC, and there are also strains that are more like 3:2 (example, like 9% CBD, 6% THC). Harlequin is one of the well-known ones. Leafly categorizes it as a sativa but I wouldn’t put too much stock in the sativa/indica thing. In my mind the differences more come from (from most effect to least): the mix/proportion of cannabinoids, what temperature you heat the weed (i.e., vaping vs. smoking), and what terpenes are present.
On weed and sleep… Everybody’s body and experience with how weed works in them is different, so I hesitate to offer any definitive statements. I’ll note that for me, weed isn’t a magic bullet for my sleep issues. It is the case that, when I’ve used weed, I don’t wake up at 3:00 and struggle to fall back asleep (which is something that I experience somewhat regularly), but at the same time, the sleep that I do have feels less restful than a good night of “sober” sleep.
So… shrug emoji… Hope that helps a little. Feel free to come back with more info about what you’re after and maybe we can come up with some more ideas.
