My weakness issues started for me shortly after childbirth, too. And like you, at first I chalked it up to being a new parent. Did you have an uneventful delivery? My daughter expelled meconium before delivery, and I had an emergency c-section. I've wondered what may have acted as a trigger.

I also have a lot of fasciculations, but they are not continuous like in Isaac's. They jump around in random places as well.
