I have just taken my pulse several times (sitting down on the sofa) because my heart felt like it was racing. I though it must surely be in the hundreds as it seemed so fast. I took one reading of 79 (I was feeling a little anxious that might heart might be racing) and then a couple more. The last one, when I'd calmed down and realised my heart isn't "racing", was a very respectable 64!
Now, that might not seem particularly remarkable to most people, but for someone who is used to her heart rate dropping into the 30's when relaxed, 64 is positively racing!
I have to say I was quite worried initially that I was over-replaced but I actually think I am near my optimal dose now. I do wonder if perhaps the high dose sublingual B12 is also helping. It is since increasing my dose to 5000mcg that I have noticed the biggest change. I'm also feeling nice and warm at the moment, like I should be.
Now to get the rest of my energy back and lose some weight!
