Oh good, Nanc - I was just going to ask if your Dr has given you anything for the nausea. So, you have the phenergan on hand. Good to hear.
I hope something will help you get rid of those nasty headaches. There's actually a forum here at NT on Headaches....Maybe you'd find some ideas or suggestions if you peeked over there. ?

And the driving, yes, I think most of us have confessed that we do drive with the unit on. The manufacturers say 'not' to have our units on while driving to cover their rears, just in case something would happen. They don't want lawsuits.
For long distances, some of us claim that's when we need the unit on the most. But in your situation, driving on a busy highway with crazy drivers, I think you are wise to be cautious about this.
