Hi Liberty, are you able to get out and walk for 20 minutes? Or even 10? I have a bike and somedays I can't go out at all, but I live close by a park and I just ride around there for a while. I actually find biking (on even ground) easier than walking. If I feel weak, it seems easier to sit on a bike then carry my weight around. Not in heavy traffic though. With brain fog, I wouldn't advise biking in a city on streets with busy traffic. Never mind a car hitting me, I feel that one day I'll ride into a parked car, some days I'm so out of it! I know that's probably not much help, but if you can get to a park or something. Even walk around the block a couple of times. I borrowed that book you recommended in my thread. Thanks. Take care.
