Yesterday I had planned to do some necessary errands. Then suddenly that morning I got dizzy, really dizzy, unable to walk let alone drive. After three hours of that, I got a belly ache. Blood glucose and blood pressure both okay, so I don't know what happened. On the other hand, unexpected problems of some (usually diabetic) sort crop up often enough that I hate to make any kind of appointment or commitment. I truly admire PWDs who actually get off to work every day. Does anyone else hesitate to make plans?
