you are back on the effexor are you? it will be a big help if it eventually works for your anxiety
its always hard to know if another new problem is a side effect from an antidepressant or not
trazodone wasnt a good choice as a sleeping pill as it doesnt work for everyone, it sedates some and stimulates others, the valium type meds are a reliable sleeping pill
if the effexor is stimulating you, take it on waking typical dose range is 75 to 375, it will need to be at 75 or more to be effective, if on less now, gradually work the dose up
as always, learning relaxation and CBT also helps
