Cymbalta and feet legs

I took my first Cymbalta this am and it is like nightmare starting all over again. I took Wellbutrin for about 6 years and several times a week, when I tried to go to sleep, my hips, feet and legs would begin to hurt. Then every time about 3 seconds after I'd actually fall asleep I would have a severe myoclonic jerk and scream out. This showed up on a sleep study. The doctor showed me and my husband the video. He said it was the strangest thing he'd ever seen and planned to take the video to the next conference he went to. Everyone, pharmacists, doctors and neurologist said it couldn't be coming from medication. The sleep doctor put me on Ambien CR, but after almost pulling out in front of a car that I swear wasn't there a split second ago, no more ambien. Another doctor put me on Clonopin which has helped. After going on Lacmictal as a hormone/mood stabilizer and tapering off Wellbutrin, after almost instantly six the myoclonic jerks totally stopped. Was doing well until increased the dose of Lamictal from 100 to 200mg. Followed package increased as instructed. At 200mg felt like ants were crawling all over me. Immediately came back down to 100, then to 50 then to 25mg. No lunch. Stayed off of Lamicatal for about a month, and tried 50 mgs. Still itching almost as soon as I took it. Am doing pretty good on Clonopin for complex PTSD and Concerta for ADD but still have depression severe mood swings. My new Doctor insisted Cymbalta was exactly what I needed. After just one dose the myoclonic jerks started again. Had 5 in about 30 minutes, again, 3 to 4 seconds after I go sleep. And my feet, legs and hips hurt again, every time I lay down. Is there no end to this misery? It seems you just cannot win. I just need to vent and find another sympathetic soul who has been there. I think my husband has had about all he can take, and I can't say as I blame him. Thanks for letting me express my frustration.
