I have always been able to count of ativan lowest dose to help me through long car trips or dental visits. I had never had a bad reaction to it until lately. The last 2 times I've tried a small dose it has had a negative effect on me. It seems to make me feel off balance. I don't take it often maybe once a month. Could it be the tablets get old after a few months? I'm older now so maybe that's a factor. McClezine type drugs do not work for me at all. My physician only knows Mcclezine. I need something this week. Any suggestions what I can do to get through this? Thanks.! You can see why I'm in a panic I can't go anywhere without something to calm my system.
