Did anyone turn into an emotional mess upon starting b12? After taking HydroxyB12 2000mcg sublingual lozenges for two days, my potassium tanked and I ended up in er. After that, I decided to start low and slow, taking 1/8 of a lozenge as well as potassium supplements (spaced out). Well last night I had the most bizarre reaction...cold body temp, teeth chattering, and uncontrollable crying. It was like I was a different person. Today I feel better but toes still feel cold and numb. Could this be from potassium? Or is this the b12 itself? Does it affect thyroid? I feel like I’m going crazy.
