Yes, after a while it gets to the point where it's hard to know what's causing what. My pdoc just added an old blood pressure med to the Cymbalta I already take. This old blood pressure med, Clonidine, is given nowadays to people with PTSD. It's supposed to calm nightmares. So far it seems to be helping... I've only been on it for 4 days now. But I've noticed a couple of new symptoms over the past couple of days. I get this kind-of fluttery feeling on the surface of my chest when I'm outside working or walking our dog. It's just on the surface of the skin not inside as though it were something involving the heart. Of course, it's also only been the last few days that the weather was such that I could do much outside. Anyway, now I don't know if this is related to the new medication I'm taking, the combination of the new med with what I've been taking right along, or something else altogether. It's a conundrum! Perhaps the neurologist will be able to help you figure out the reason for your time loss... hope so!
