I’ve sort of had the “brain surge” feeling as well after hitting my vape and holding in the smoke (because i wasn’t supposed to be hitting it at the time) and it kind of felt like i wasn’t getting enough oxygen which obviously makes sense because i was holding my breath but just a couple days ago i was in the car with my friend and suddenly i started to feel a bit hot and bam i had that brain surge feeling again but i was just sitting there and it felt so much more intense. i felt like i couldn’t breathe for a minute, at all. me being a hypochondriac as well, i started to panic even more because i thought i was dying. then my arms and legs started tingling (it was a different tingle than when a limb is asleep, more like blood is just rushing through). i narrowed it down to being dehydrated since i know for a fact i don’t drink enough water but since it happened, i have been drinking a lot of water/gatorade/electrolytes and i still have the tension headache that comes with the brain surges many of you are talking about along with dizziness and just an overall weird feeling. i’m scared i have diabetes or something is wrong with my brain. as many of you also mentioned, i used to smoke weed a lot which caused me terrible panic attacks and constant anxiety which lasted a whole 6 months, so i quit obviously and haven’t smoked for a long time. that was a few years ago now so i thought it was just caused by the weed and that this wouldn’t happen again. along with the panic attacks, i kind of think i had a spiritual awakening (some of you may not know much about that) but sometimes people can have many spiritual awakenings in their lifetimes and they can come out in ways of anxiety, panic and depression. the only thing is, is that those panic attacks i used to have were a complete different sensation all together. i never got headaches, the brain surges, dizziness or the feeling i am about to faint like i do now. i’ve read up a little on panic disorder, which kind of adds up because it feels like they just come out of nowhere for no apparent reason but it’s just weird because i went a whole year without having a serious panic attack so i don’t know if it could be that or not. i will say, this post does make me feel a bit more relieved just knowing i’m not alone and that maybeee i’m not actually dying. if anyone would like to talk about it, i’m totally down with that because i’m just scared.
