Precisely! Shkoyach!
I asked a sheilah once to a well-known poseik about taking something to help me sleep at night on Shabbos (I had recently heard a recording of a shiur in which it was mentioned that it’s a machlokes.) The Rav said that it’s assur. So I asked, “but isn’t there an opinion that it’s muttar?”
So he said, “Wait a minute.” He went and looked it up and came back and told me that I can take it if I really need to (I do).
Disclaimer: I am not suggesting that one make a practice of shopping for leniencies. I am talking about those situations in which there is more than one valid opinion, and there are factors that may make if difficult for the person in question to go by the stricter opinion. They should make sure to mention those factors when asking the sheilah.
