There are times when it's just not safe for me to drive. If I'm at home and already DP'd, I try to avoid going out. If I'm already out and an episode hits, it's a judgement call. Sometimes I can safely function through it, other times I cannot and I have to wait for the severe episode to pass, or call my husband. I've only had to call him a couple of times - usually the bad episodes pass within an hour. The thing that gets tricky is trying to function through the periods where I'm DP'd for days on end. We still need toilet paper, you know??!
