About 10 years ago I was in a similar situation. (I was hit from behind and had serious back problems but I was only working part-time so I had no sick time to take off.) Like your husband I continued to go to work, which didn't help matters because I couldn't even lift my arm to reach a counter.

I know that only he and his MD can make decisions about his care, but if the drugs are making him really loopy maybe he should talk with the MD about taking a class of drugs called NSAIDS (aspirin like drugs but stronger). They have other side effects, but at least they don't have the loopy effect.

I also sued the other driver and it took almost 3 years before it was settled. The only reason it was settled then was because I was moving out of the country. What I want to say is that sueing is a long and involved process. If you aren't sure what you will get out of it, you should think about it twice.
