Other times. Had them first (or noticed them first) about 2 years ago when I stepped up the training. I loaded up on magnesium last night and they're gone. I must have rather variable Mg levels depending on how much I sweat and I forget to take Mg.

I had them checked out, including an ECG, they're annoying but nothing to worry about.
