Melatonin had the opposite effect on me; it made me anxious. This was before I knew it was contra-indicated for auto-immune diseases. Obviously, my body was telling me this!
The only way I can truly get good sleep naturally, is to exercise my body. A 3 mile run/walk, an hour of pilates, cleaning house, brushing the dogs, running errands, cooking from scratch, organizing/reorganizing, etc. The problem with this scenario is that my body can't do all that anymore, every day. My body needs to be worked out in order to obtain sound, natural sleep. In the absence of the level of physical exercise I need but can't get, Ambien helps me get the sleep I need. Mirtazapine also helped when I lost so much weight and sleep.
I know there are not many advocates of using meds in order to sleep (z meds in particular), but I'll do whatever I need to get my zzz's, otherwise, it's a crappy day ahead and life's too short for any crummy day I can avoid.
I don't care if my GP/Rheumy, etc. say that insomnia is not a symptom of SJS; my body is telling me otherwise. They say the tinnitus, loss of taste and smell that happened when I had my flare is also NOT a symptom of SJS but since there is no other disease it can be attributed to....and I hear from so many on here that they have suffered the same...it must be part of Sjogren's. I am so tired of doctors saying that symptoms I have (other than dry mouth/eye) isn't consistent with SJS, I just have to shake my head and realize how much doctors DO NOT know. Sorry this turned out to be a vent!
