I posted previously with a few questions about this....I have epilepsy. My concern is standing for long periods of time in the heat; however, my concern is that it could induce a seizure or other issues I have related to my epilepsy. Will they suggest I just get a wheelchair because I can walk with frequent breaks? I don't want the issue of having to pay for an ECV or making my wife push a wheelchair around all day. I don't plan on using the DAS but would like to have it if I am having a bad day.
