insomnia
"I have been on Effexor XR for years to treat depression and klonopin for anxiety but didn't sleep at night.  Dr added Remeron to the mix.  I took it for almost a month.  Tho it did help me sleep, caused severe hangover next day and zombie like all day.  Stopped taking it.  Dr convinced me to try again.  I did, ended up with sudden onset hypertension and tachycardia.  Passed out, had to be taken to emergency care.  Blood pressure dropped rapidly as did my heart rate.  This is known as  blood pressure lability.  Can never take this med again.  Still suffering affects, pounding headache, vision issues and can't get my blood pressure stabilized.  Terrible for me!  Never again!"
