Claire,
You can work up slowly to almost anything!
For driving I would suggest the following baby steps...
1) Visualize yourself sitting in the car, starting it, driving it, coming home safely.
2) Actually sit in the car, start it, drive it out of the driveway only and increase the distances progressively.
For taking vitamins...
1) Talk to your doctor & ask questions
2) Talk to your pharmacist & ask questions
3) Talk to other people who have taken this medication (Support group members ;))
4) Practice with "fake pills" such as frozen peas. Practice the act of swallowing the "pill"
5) Practice holding the pill in your mouth
6) Take the pill
Don't forget to use your thought challenging tools & distractions as you go along. You can also adjust these according to your preference of needs.
