I'm going in for autonomic testing in the morning and they are admitting me so I can try different meds. Not really happy about that. In the past when I would be like this, just not as severe. I would come out of these episodes slowly. I have been doing leg exercises while laying but nothing is getting better. I have never felt like this. I'm also a long time smoker. Bad me I know but it used to help except when I was in an episode I wouldn't smoke that many. I thought on great nicotine withdrawal on top of it but I feel horrible if I smoke one and if I don't. I just don't do well with any meds and this is frightening! I have been in the er all day and they have not given me fluid or even a cup of water. Thank you so much for your response!
