I wonder why you had that reaction to MB12.....(snip).....Which MB12 are you using ?
Wish I knew. It just started suddenly like a niacin type of flush, burning, very itchy skin and red patches. I thought maybe something to do with histamine and oddly, I upped the dose back to where it was the last 2 nights and didn't have reaction. Maybe just a fluke(?) I'm taking the Jarrow brand.
Before I got on this forum I thought there was only one type of B12, cyanocobalamin.
At one point, it was interferring with my sleep, but so far so good this time around. I was also getting a toxic reaction to the Solgar P5P but I'm doing better with that one now too. (I hate to even say this, but after my episode of food poisoning I could handle these .... I'm just saying ..... something about my digestive tract improved after that ? )
How was it interfering specifically? I find the Jarrow B-Right with P5P taken with Folapro makes me sleepy, so I take them right before bed. Last couple nights, since upping the Methyb12 again, I have woken up at 3 am and had some difficult getting back to sleep. Maybe a coincidence or maybe not.
Are you still taking amino acids too? I'm pretty sure you wrote that you were taking Solgar (unless I'm thinking of someone else).
My orthostatic intolerance starts as soon as I stand up and just gets worse to the point where I HAVE to lay down ... and usually for an hour.
I'm lucky because my POTS/OI is variable, worse some days and not too bad others. I don't know the reason for that, I suspect hormonal implications. It is worse on a day that I have pushed myself too much tho. That makes it harder to pace activities at times because I'm clearly different one day to the next. The POTS/OI has been the last hurdle, the pain, PEM and cognitive aspects are greatly improved. Not to say I'm 'normal', but much better than I was.
I agree exercising should be done laying down. I need to do more of that, but at the moment I'm getting my 'exercise' from doing more daily chores like cooking and cleaning a bit. Thankfully these chores have gotten easier and I attribute the Adb12 primarily for that.
The pool is nice because I can float, but it is easy to overdo it. The yoga is for people with health problems and last night I did attempt a standing pose for a bit, but the HR monitor let me know 'hey dummy, you are not as healthy as you think you are - sit down now!' LOL
I don't know how you are doing sit-ups, they make me feel nauseated lifting my head, but I equally want to work on my core.
I was taught a modification in yoga that has helped me.....I'll try to explain it incase it helps someone else. Sit on the floor, arms at side w/hands on floor for balance and bend legs at knees. The standard exercise is to then lift one leg (or both if you are strong) slightly off the floor and feel abs working. I've always had trouble with this because my low back is not strong and I collapse forward, rounding my back and putting pressure on my low back. I was taught to put a medium sized ball (found at dollar store, not a large exercise ball) on the floor behind right me and lean into the ball. It will add support for the back, but you will still feel the burn. You can also lean on the ball and shift slightly to the left or right and work the obliques.
This image somewhat shows the stance, but imagine the ball on the floor behind the guy and him leaning on it for support

I hope you keep improving and keep the forum updated.
