If can my own story that probably has no basis in fact but is a good story non the less
I have heard that someone went over to Reb Dovid Feinstein and said ” I heard that Reb Moshe drank Cholov Stam and threw up” and Reb Dovid replied “Both stories are true, Reb Moshe drank Cholov Stam and threw up. Not at the same time though.”
