That differs to everyone. With traveling it varies on the person and what their Epilepsy/seizures react to. What forms of traveling, is your body able cope with. Like, Traveling by……..
1 car / bus
2 Train
3 plane
4 Boat or cruise ship

Then there is the change in …..
1 weather
2 change in climate
3 change in the Environment
4. Changing from land to sea and sea back to land
5 change from light to dark and from quiet to noisy
These are possible things , that may trigger seizures. Doesn’t mean that you will seizures. Doesn’t mean that any of these will trigger yours.
With myself , I am able to cope well, with all these different things .

Overall , make sure you have a full stock of medication, for the amount of days you’ll be traveling from home.and back .

Wear a medical alert necklace or bracelet. If you are not comfortable being alone go with someone. Let the airline aware of your situation.

Happy birthday

I would say, it all depends on how severe your seizures are and how often they come on aka whether their controlled or not, personally I drove until I moved back to New York State and had my license revoked,
But before that I used greyhound amtrak and airline's admittedly those 3 options are a pain in the butt, but they are safer for someone who has uncontrolled seizures and in that case I would recommend traveling with another person as often as possible

Randy did a great job! When traveling out of the country. Have paper prescriptions from your Dr(s)! That helped in Egypt, France and England! I bring my supply but immigration wants proof you are in need of medications.
