Hey Ouch,
Try not to be worried, re: Trazedone.....not bd med; gd results -- i.e., better sleep (for me, anyway). Just drink a TON of H2O & monitor your sex life/adverse affects....
Can't say I know much re: Lithium, but all the best. I recommend you take conscientious notes re: Lith.
Best wishes from a fellow T.dotian,
