I know 100% I had ms for sometime befor DX. I have always tried to stay in when hot and in when cold. That is just me and I know now due to ms. I do not think I would like the weight. My advise is to check all sites, ask for advise (all u seem to have done) or are doing - pick out one - and hold off till u know you need it. We are from everywhere, and all walks of life. What is ok for me may not fit your life.
