Bruno, I really don’t have time this morning to list all of the meds I am on but if I were you I’d listen to my Neuro. I am on Lyrica and thats the way they start it. It is one that they gradually incress the dosage. In a quick list I’m on Cymbalta, Lyrica, a few other pain and muscle relaxers among a couple of suppliments. My Neuro has had several GBS patients and he’s a very good one. I’d be driving myself crazy if I started to try and second guess this on my own. I thought the “zings….” were nerves waking up and he told me it was just bad signals from the damaged nerves. There are so many things in our lives that have been changed.I’m trying to accept some and improve others. Of course this is “MY” opinion and we all have them. Hang in there and never give up.
