Hi rot gut,
I too am on MTX and have been on it since the summer of 2007. I seem to get a little more tired for a day after I take it. I started out taking the pill form and have been injecting for the last 3 months. I take 20 mg and have not had any other major side effects. My liver function tests were a little off but I get blood work done monthly so we keep a good eye on it. If you have any questions feel free to ask. This is a great post you will get a lot of support.
