I'm finding that I can increase the dose every few days, so I am now up to 2mg B12. I'm on 200mcg Metafolin: does anyone know if I'm likely to have to increase that? Because it's a nuisance cutting the 800mcg tablets into four, and I'm eyeing up the 400mcg tablets.

One curious effect I'm noticing is that I seem to be retaining water. I never retain water. I deliberately lost a quarter of my body weight the other year, and I was the only one on the dieting forum not grumbling about how the scale bobbed up whenever they ate something particularly salty or were premenstrual. (Which was particularly odd since I get premenstrual breast swelling, yet my weight continued to saunter downwards. I concluded that they were inflating with air.) Now, however, I am retaining water in quite a noticeable way. I know that people with POTS start to retain more water when they are put on Florinef, so I'm wondering if I'm getting a similar effect from the B12. Does anyone know more about how this works?

It's hard to tell how I'm doing on the B12, since we're having something of a crisis in my block of flats and it's been quite exhausting. You know you're having a bad day when you reflect, "Well, the good news is that the smell in the basement wasn't a dead body after all." Either I'm still running on adrenaline and due for an almighty crash, or I'm coping with the stress and exertion remarkably well.
