Been out for a hour

Well after more than two weeks I have managed to get out of the house. Having spent most of the day asleep I succumbed to going out for a drive and am now back home exhausted. I need to be able to go out as I want to go and see the doctor next week. I know that any surgestion I have something wrong with me will be put down to my MS. but if I dont ask how can I get anything done? so wish me luck I expect I will need it.
