I don't know if the Melatonin is getting me to REM or not, but when I don't take it, my sleep is not as deep.
That list is scary, and the chaos and night terror types of dreams are exactly what I was experiencing while taking Cymbalta. The depersonalization is another one that really hit me. I was so detached from my family and friends, (my daugher lives right next door) that I would go weeks without seeing anyone, and I didn't really care. It became ever worse when my dose was increased from 60mg to 90 mg. For some reason, when I hit 90, and things got worse, I had a lucid moment that said loudly, "this isn't normal, get off of this stuff!!".
It is also scary thinking that the pineal gland maybe isn't repairable. I can't imagine my sleeping being like this forever. I hate to even go to bed because it is always a miserable experience. At least having my dog next to me is somewhat soothing.
Unfortunately, I don't know that there is much we can do, even collectively, to try and prove that Cymbalta has done any damage, because Lily can always fall back on "well, these people were depressed to begin with". It is frightening.
