yep i recently got it from E when i was just about to fall asleep. Problem was....i had recently seen someone because i was having problems with my heart.Eg heart pulputations and shite. My heart would like beat...beat....beat....beat....mis-a-beat!!?.....beat....beat.... I saw a irridologist and was told i had a HIGHLY overactive tyroid gland.....its the gland in your neck which controls a load of things especially metabolism and heart rate. Basically my over active tyroid was screwing with my heart rate. And i was borderline graves desease!

when that happens they have to cut the throid out and give you pills the rest of yourlife because your body just starts attacking the gland
ANYWAY...i was freaked from the electric shocks cause i SWARE i thought it was my bodies way of jolting me awake because my heart had completely stopped. I would come home and simply dread falling asleep. But no matter what happened i would think my heart stopped every time i jolted awake....to add to the problem my GF was in Japan for 3 months so i was feeling uneasy about being in bed by myself

It was like i was all alone in big bad bed!

By yeah its all sorted now soo???! i dunno.....what i definately do know though is that slowing my overactive thyroid gland down did fix me up almost straight away.....
Ive also been told recently that i had abnormally high blood pressure for someone who is 22. This could have been related to it also. And maybe when your sitting awkwardly from smoking pot it does something to your neck and builds blood pressue around the base of your brain or spine or something? Maybe increased blood pressue adds to this?? i dunno..... But anyway my pressure is bad down too now.
Oh yeah i also used to get the jolts REALLLY bad from smoking pot day in and day out. I remember i would worry about my neck when smoking...it was like when high my neck would just hurt....it was like stoning would make my neck hurt just to make me quit....i also got paranoid heaps towards the end of my pot smoking career :D
Yeah but i would get like MAJOR jolts i remember once i had a jolt soOOo bad the jolt ran through me...my ears rang....and my vision went a deep dark purple for about 2 seconds in a big flash....it was as if id been struck by lightning.......and no it wasnt due to low blood pressure when you stand up suddenly or low blood sugar. I was majorly freeked out.
Atleast im ok know...and i hope all you ppl can find out what it is too. I suggest seeing a irrodologist?? or see a doctor and have a blood test to determine if your thyroid gland is ok? Generally if you can't put on weight to save yourself then its overactive and ofcourse if you put on heaps of weight then its underactive.
Hope i didn't shit on too much.
take care,
ROb.
