Hi Kate,
I've recently had one sleepwalking episode, and mostly just episodes of passing out randomly (almost like narcolepsy)... I was hospitalized for a multiple sclerosis exacerbation recently and I am on high doses of oxycontin, zanaflex, neurontin and Cymbalta. Oxycontin is very similar to your MsContin and Zanaflex is very similar to Baclofen. Endep or Amitriptyline acts primarily as a serotonin-norepinephrine reuptake inhibitor, which Cymbalta does too. So I wonder if the combination of all these drugs does this?
At first I tried cutting out the Zanaflex yesterday, but hadn't realized I also cut out the Neurontin and Cymbalta on accident. After I took the Neurontin and Cymbalta yesterday, I noticed that I started getting unreasonably drowsy for 4 o'clock in the afternoon. So, I don't think the opiate and the muscle relaxer are doing it to me alone. Today, I'm not taking the neurontin (I don't think it's helping anyways), we'll see where that goes.
I took the Cymbalta today. I'm crazy, so don't try this at home
Definitely talk to your doctor. I just left a message for my neurologist and I see him on Monday. This stuff is really scary. I do admire your sense of humour though. We have to have one when faced with these chronic, incurable diseases.
Cheers,
Charley
