Zoloft and dramamine bad together?

I took zoloft for the first time this morning, and I was unable to fall asleep due to restlessness. I usually take one forth of a dramamine to make me drowsy enough to sleep when falling asleep is difficult. I finally got to sleep, then 2 hours later I woke up extremely restless and I'm finding it very hard to keep my arms from moving. Are these two drugs bad together? What can I do to make this go away?
