My HMO's mainstay treatment of FMS/insomnia is low dose tricyclic meds. Have tried Flexeril/Nortriptaline/and now Doxepin...all with poor results...i.e. even more insomnia,depression, hangover, irritability,etc. I am told I should not continue very long on Klonopin ie tolerance. What a bind. Has anyone out there been helped by tricyclics? Thank you.
