Oinky, since you started as Insomniac, did you find out that you were a wolf, or did you just find out you had been switched?
If it was the former, you might have tried to convince Drogo that you were originally the Minion once it had been revealed that you 2 were switched. The real minion wouldn't have contradicted you and Drogo might have decided not to chance outing you. You'd still have to reveal "the wolves" but you might be able to convince enough people to lynch an innocent townie of your choosing.
All of the above is probably a long shot though. As Silver said, I think you were just kinda stuck with a bad luck situation.
