the next time you’re sitting on the toilet a little constipated - might i suggest some acupressure.

press on ST 25 (pictured below, cun =~ 1 width of your thumb)right then left then at the same time & then rub up and down, with slight pressure, the lateral lower leg along the anterior tibialis muscle. making sure to rub ST 37 and ST 39

let me know how it goes!
