Thank you Chris. So far husband, to me, has had negligible side effects. He has sweat on his forehead at times, but sleeps the same. He does all the same things. I'm afraid we're night owls and got to bed about 12 midnight most nights. He walks several miles a day. Hes been to the allotment today and is cooking dinner and getting ready to take a neighboyrs inexhaustible dog on a ling walk, despite the rain. He has now got ED but Sildenafil 50mg is still working fine.. He has taken to using the vacuum pump after a shower, and commented how well it was going today. He's definitely not shrinking at present. He does have high BP, as do I , I think the result of 40+ years teaching and caring for a son with a " severe enduring mental illness". He very non emotional, which is why we work so well. Because I'm high emotion. I just hope we can cope with any extra changes.
