I sleep about 8 hours with the help of Trazodone and then wake up to inner vibrations and extreme anxiety, I have days in between where this doesn't happen, all of this made worse by taking Doxycycline for Diverticulitis, I was beginning to feel much better, fewer attacks and then I had to take Doxycycline, I finished the Doxy two days ago, and this morning no panic attack...hope this continues, no fun.
