I thank your both for your help. Don't think the problem has been pinpointed and Im thinking very seriuosly about ending my life at this point. I really don't want to but I have a problem with dizziness and vertigo since many years and this pressure worsens that as well (its 24/7). The thing that helped the vertigo, clonazepam, gives me insomnia these days post appendix-surgery. NO IDEA why. Oh well such is life I suppose. I have such extreme anxiety about all of this bleh, wish I could feel some peace at least.
...reading this thread with interest, though much of it is over my head. Vertigo, however, I have had experience with, and I can sympathize knowing the utter helpless misery that can cause.
In my case, the relevant inputs were piracetam (1800mg/day), Choline/Inositol (250mg/250mg/day), genetic low blood pressure, and hard exercise with 5-hour energy drink. Normal condition is very healthy and stable, though prone to dizziness after exercise, when blood pressure is quite low.
Anyway, a couple months in I had an episode of vertigo that was horrible - spinning room, throwing up, laying on the floor motionless pouring sweat, I thought I might have been poisoned and was dying. It lasted about three hours, while I tried to go over everything I did and didn't do, but didn't really figure out anything. Searching online I came up with vertigo as fitting the symptoms to a T, and acetycholine as one part of it. Lacking any other idea, I ceased the choline/inositol supplement (eating an egg with breakfasts then to make up for it).
A month later - same thing, miserable vertigo, on the floor sweating and vomiting for two hours. Slightly less bad, and knowing that I wasn't dying was good, but still the fear that something unknown was going wrong with my brain. Then, I figured out that both of these attacks had happened on weekend days, when I stay home and make a good pot of coffee. At work we have the cheap watery stuff. And then I also related a suspicion I had already settled - that 5-hour energy drinks had stopped working as physical stimulants, but made me feel sickly instead. One or two a week was all I used, but I had already stopped these by the second attack.
Talking to my mother about it, she confirmed that she had mild vertigo problems at one time, and had solved them by cutting out caffeine. So...now a couple of months with zero caffeine input, and I haven't had any recurrences. I hope this might help, but it is hard to sort out influences when there's an array of possible culprits. In my case, just changing physiology with age, and perhaps genetic predisposition seems to be the cause of the caffeine sensitivity, and (fingers crossed) all seems good for the long-term again.
