Because I'm now 80+, my GP says " Stay on it ! " But I am always exhausted and don't believe old age is the main cause ! No other illnesses and a happy marriage ! Would like to at least reduce my dosage of 150. Do have stressful situations eg recent divorce of one of our children and find I can't cry when on this medication, which is horrible somehow ! Sounds a bit contradictory, I know but want to feel I am in control of my moods... Is there anyone of similar age in this situation ? I also take a statin and beta-blocker for high b.p. and high cholesterol. Sometimes feel I'd be fitter without any of them !
