thanks guys my problem with midodrine is that even if i take it half an hour later than more normal time i would i totally crash. i would even be better off if i didnt even take it. i also cant handle the three doses a day. i feel all wired out by the time i hit my third one. I am really anxious to start my hydration therapy because every time i have had an IV in the hospital i felt SO MUCH better the whole day. I guess it just really ***** when you find a medication that actually works and then it stops. I can handle trying something new and finding out right away that its not for me, but when it just stops working one day it really bums me out. I guess i just need to not get my hopes up anymore. Sorry for the sob story i am just so frustrated at the moment and my POTS is worse than it has been in a couple years.
