Im 56. It did give me a mild headache when started taking it.
Important: If you aint horny, no amount of cialis will make you hard. It is an aid for when you ARE hard for normal reasons. So when you do get your normal hardon, it will be fuller. You will feel your cock slightly heavier. Its funny but it makes you feel like you are a BBC haha. Try it for a month or so and see.
For instance, as soon as wife got dressed to see a lover, I would have a hard on until she came back the next morning. These days, Im indifferent. But with Cialis in the bloodstream, I do feel my young self again.
Generic name is Tadafil.
Be careful if you take pressure pills like nitrates. the combination can send your blood pressure dangerously low; so I read.
