Clonidine
perimenopausal symptoms
"Have been having hot flushes for years at night  which are getting worse.  Tried HRT for years but had to come off because of my age.  Chemist suggested I ask Doctor about this drug.  After 3 days I couldn't keep my eyes open. I managed for 4 hours then went to sleep for 4 hours.   Hot flushes don't seem quite as bad.  I only hope that this tiredness and drowsiness goes.  Cant be doing with this."
