Thank you, these have been helpful.

I went into work to do some odd projects to see where I am. Well, 6 hours done over three days and it took me a day and a half to recover. I couldn't look down the street at night (street lights too bright), headaches, confusion, stuttering, and I felt like I was foggy and drunk. So I guess that answers that question.

Funny thing, right as I realized that this is the right choice, I got an email from work stating that they will have to replace me until I can come back to work. I am fortunate that they are so supportive, and will continue to give me side projects that will help me.

I too have found that repetitive tasks are easier, and require less recouprative time.

Humbling, yes it is. Right decision, I now see that it has to be. And I am happier knowing that if/when I can go back to work, my job will be there.

Thanks for the input!
