Shift.ms is better if you're logged in

I've noticed in the last month that I have trouble peeing. Up until then I was going fine. I can sit on the toilet and nothing happens. I had to go and see my ms nurse last week and she mentioned switching to decaff tea and coffee. I started that Sunday just gone and yesterday I was peeing a little better. I hope it is water retention because I do not fancy self catherization at all. Does anyone else drink decaff and noticed a difference?
