Does anyone have a low resting heart rate along with a history of low b12.
Mine runs at low 50's while I rest on the bed then climbs to 70-80 while i move around.
I tend to feel much more tired at times when it's slow.
After I shower on a morning it climbs to 100-110 when I get dried but as soon as I lay down it drops back down to high 50's-60ish.
Does anyone else have a similar experience?
