 First of all, no. Don't do it. No one deserves that. Please do not do that, especially in public. But number two, own up to it. Be a man. Claim luck. Whatever. Whatever reason that led you to think that the best course of action for you in first class on a long flight was to do that, just own up to it. Don't try to blame your diet and try to blame some shrooms to leading you to act like an idiot.
