Does anyone experience intense pain around the neck withdrawing from cymbalta/Duloxetine? The nausea, headache, pain in my bones, insomnia, brain zaps; feels like I'm licking a battery! How long does this go on for? Ive been off it 1 week and not slept before 4am which is great when you need to work etc! I wish the gp had warned me of the withdrawal I would never have taken it.
