I'm like chooca, except, treatment resistant ultradian w/mixed state. NOTHING works. 25 meds in 21 years. And Klonopin is losing its punch. Just completed in-lab sleep study because research is showing that close to 50% of treatment resistant rapid cyclers have some form of sleep apnea. See your primary or a sleep specialist if you don't need a referral. My insurance(Aetna)wanted more info before approving it but when they saw my two sleep survey scores and my medical history, they signed off on it in less than a day. I can only hope that the test results are positive.
