Hi Tayisa...I am also tired most of the time, it's terrible isn't it? I have trouble sleeping and take Trazadone, and have found that also contributes to my fatigue (Trazadone). My mom took Amitryptiline (sp?) sorry! and one of the side effects was fatigue or sleepiness from the medication, so that could be contributing to some of your tiredness, you may want to check with your doctor. Although most of it is probably from the RA in general
I have found the only thing that combats it for me is pred, and that is not the best thing for it.
