i'm sorry you're feelin' bad Barbara. hope that headache goes away. if it's your blood pressure though, walking should help. do you have one of those machines to check it yourself when you get back home? or maybe go to a drugstore if you have one nearby.
ironic you say coffee doesn't agree with you... it can actually help my headaches.
well anyway i hope you feel better. perhaps the walk will help.

and then maybe resting a while after you get back home.
i'm playing mahjongg solitaire right now... gotta keep the brain trained at least, if not the body!
