My friend, as he told me of late, he never had this with oral aya - farma, but since modest vape experiments he never got landed completely again. The buzz, is there too but no probs with that, but this energetic head spin feeling (not physical) as if he's a tad high just wont go away. It feels okay to have, he says, it comes with this particular feeling in the head between the 2 temples, no headache, just some sort or re-wiring feeling, a plug-in into something, seems to be definite. He has no regrets, but completely sober feeling looks like something from the past. All is functional, no pain, just weird head feeling, feels kinds cute but he never expected this. Something familiar?
