Since beginning methotrexate ( 20mg) I find it increasingly difficult to get to sleep . I know I'm tired but when in bed find I'm tossing and turning and have "jumpy" legs. Has anyone else found this? Find myself becoming very frustrated. It's Xmas eve tomorrow and I've a thousand things to do and annoyed that I've come to bed early to ensure some energy for tomorrow - and still tossing and turning!!
