You've probably already figured this out, but those mart carts at stores can be a lifesaver. When I'm feeling particularly dizzy, I make use of them so I can still get crap done (no, the kids will not magically have food to eat just because I feel like crap). Granted, I also use them when my arthritis is acting up enough, but I wanted to let you know that yeah, while I don't faint, my vision can black out when I'm dizzy, and have found the mart carts useful.
