That’s interesting - I wasn’t aware of the vision risk there.
Personally I’ve found tadalafil modestly helpful. It is by no means a radical improvement. There is no change in libido level - it just improves bloodflow somewhat.
The vision risk would be enough to put me off taking it every day.
Cialis does nothing either standalone or combined with tadalafi, for me. Cialis does seem to have some undesirable side effects - vision changes, feeling of blood pressure increase… after trialling it out, I don’t take it.
