I feel the same way sometimes. I will be standing in the store or anywhere and I have to grab onto something. Alot of the times I walk like I've been drinking and I don't drink. I couldn't walk a straight line if I had to. At first when everything started happening I thought it was MS. I have a good friend with MS and she has alot of the same symptoms as I do including a balance problem. I can only guess that it just has something to do with the autoimmunity diseases.
