I actually take the 20 mg tabs every other day, Tadalafil lasts for up to 36 hrs so in theory you get 2 nights out of each tab. Also, that menschem pharmacy sends out an email each month offering 15% discount once you have placed your first order.
People have experienced strong side effects taking this dose. Either I've been lucky or my body has adapted, as I am fine. I have an hiatus hernia and scarring and have done for years, but suffer no adverse side effects from tadalafil.
