I too am having a night (tonight) where the electrical shock stuff is keeping me awake.

I possibly did get too stimulated today. I took my grandson to a movie he wanted to see, and it was a dangerous drive through icing streets. 5 to 25 miles per hour all the way home after driving him back to his home. I made it!
There are no meds I can take for this. I don't even go to a neuro, as the only one I know of here isn't so hot...there may be someone else, but my main doctors are the pcp, dermatologist, and hematologist, and that's a full plate. the only really good neuro I've experienced retired a long time ago and he was in California. Otherwise, very unproductive sessions. Yes, first one did dx MS through tests. But he left my area a quarter century ago.

Sometimes the ONLY way I can sleep is to get up, drink something hot, and sit at the puter for a while. So that's why I'm here now.

I hope your job interview is as you want it to be.
