Can i take daily cialis not daily?

Patient: Hi,I suffer from a mild form of ED and was wondering if the Daily Cialis drug can be used but not in a daily format? Does it still work the same way as the 10mg version in which case i can use it infrequently? the 10mg version works well for me, but i feel i dont need to have such a strong dosage of it and wanted to check if the 2.5mg or 5mg versions are the same thing, just lower dosages? in which case i can take those infrequently?

Doctor:
