I have always suffered from travelsickness. I thought it had got better recently, but all that has happened is that as all the roads near where we live, or on my usual travel routes are either motorways, dual carriageways or fairly good A roads, I had been lulled into a sense of false seccurity.
We recently did a five day combined car and coach tour in north Wales. Even though DH drives well, I arrived at the hotel feeling really queasy. By the end of the fourth day. I was beginning to feel travel sick 24/7. We share the driving and I drove home. I still felt sick and had to stop several times for fresh air and recovery time. It took me a week to recover and I have been getting travel sickness again regularly on even on nice straight roads and good roads, ever since.
