When I was in University about 15 years ago I would suffer from bouts of respiratory alkalosis due to anxiety. I'd feel really dehydrated and had to lie in bed for a day or two till my ph balanced itself.

Although I rarely get noticeably alkaline anymore, this is still interesting because I was just reading about how alkalosis triggers neuronal excitability which is what this neuro thinks I have.

I also read that caffeine has an excitatory effect on the nerves and makes them more apt to reach their firing threshold. I'll experiment by going without coffee next time I have a flare up and see if it helps at all.

Does anyone know what sensation/s is/are associated with nerves firing?
