I just use a Geratherm thermometer, Kath - you can get them on Amazon. Much more reliable than digital, I find. They're similar to using the old-fashioned mercury one, without the mercury (I couldn't bear to have a mercury one in the house - imagine dropping it and breaking it on your bathroom tiles...)
Yep, adrenal pain is an old familiar. I used to feel very tender in the lower back above the kidneys, even if I lay flat it could hurt a bit. Turning in bed could be agony. I got the flank pain (in the left side radiating down to hip and even down leg - like sciatica) but a hydrocortisone doses would make it go away in a few hours. I haven't had it for a while now - fingers crossed.
Your heart problem could possibly be due to the adrenals, like you say - as you know the adrenals produce mineralocorticoids like aldosterone - especially important for fluid and electrolyte balance, and as Greg said - when we start using b12 without enough b2 in our system, we get flooded with adrenalin and this triggers massive aldosterone dumping into the bloodstream, which in turn lowers potassium. The reason is because our adrenals don't work properly after years of b12 deficiency and so they don't make enough adrenalin (or cortisol if it goes on long enough). So there are tons of adrenalin precursors hanging around which get triggered when b12 is added. This is still happening to me, but nothing like as bad. So I'm not using such huge amounts of potassium anymore. And I don't need hydrocortisone to suppress huge adrenalin surges now either.
Things get dicey when estrogen is rising though (blocks my thyroid and cortisol hormones). Do you find that? Some say the b12 makes their estrogen and testosterone rise hugely (men too/testoserone). Greg says lots of things will fire up in the body and things will be in a state of havoc for a while. I would do anything for a bit of stability, but I'm very glad that things are 'firing up' so to speak
You mentioned the b group oil above, I think. I just answered
@dogged_days re what Greg told me about it being enough to cover the oral b complex needs. We still need the B12 and 5MTHF too though. I use two sprays of the b12 oil daily and one spray of the b group oil (by the way
@dogged_days, it has Ado in it - maybe you know already) - Greg told me it has 0.5mg Ado instead of the 0.65mg (.75?) per spray in the Meb12/Ado mix so it's a good one to start with for me. He said it might be easier for me because I find Ado a bit hard to take, but I will soon get the Meb12/Ado mix I think. Are you using that one now, Kath?
