Can you drink alcohol while taking lessina birthcontrol pills?

Maybe just a little: A little is usually ok. That said, alcohol is toxic to living tissues (we humans are a complex glob of living tissues) so avoid "moderate drinking." Moderate drinking is too much alcohol. Also, we get enough man-made toxins into our bodies nowadays that we don't need to drink additional voluntary toxins. It's much safer to drink water or green tea, neither of which contain calories nor alcohol.
