Midodrine for Orthostatic HT

My orthostatic hypotension is really bad. Like preventing me from doing my favorite exercises and I lose vision/get super dizzy almost every time I stand. Since my bariatric office was just like "hopefully it'll get better some day", I went to my primary care yesterday and was prescribed Midodrine to raise my BP. I've only taken two doses, but from what I understand it doesn't build up in your system... it wears off after about 3-4 hours so I have to take it 3 times per day and keep a log of my BP. I don't seem to have any side effects other than it's making my head feel REALLY tingling, like when you lose circulation in your foot or something... but "the internet" says that's a common side effect. Has anyone taken this medicine? Did it help? Do you taper off eventually or did you need it foreverrrrr? It wasn't the cheapest of my meds. =/

I tried adding salt and doing leg flexing, etc, before standing but that didn't help at all... so now I'm at the prescription option.

I'm currently sitting at my desk and rapidly standing up every so often to see if it's helping and it is. LOL. My coworker is like... wtf are you doing.... hahaha.
