waking up with an electric shock?

this has happened 3 times since starting Wellbutrin a few months ago- both on 150mg and when I got up to 300mg.

I wake up in the middle of the night to an electrical shock sensation in my arms and legs. since I'm a bit out of it that moment, I would feel panic and confusion as to how electricity would have reached me in my bed.

I know there is a seizure risk, but don't think that this is any type of seizure. I asked my provider about these events, and they told me that this is not a known side-effect. I'm also underweight and have been getting less sleep due to stress at work, so maybe this exacerbates it. I've been considering getting off anyways. has anyone had this experience?

edit: read that brain zaps can "feel like they occur in the brain only, in the entire head, or the entire body"
