You just openly admitted on a public forum to flying fatigued on a Series of 121 flights, while on IOE.. That scares the bejeezus out of me...

You are required to sign the release for each leg attesting to the fact that you are "fit for duty" per 14 CFR 117 and 121. Please Think about that very seriously. Think about the passengers you are flying around. They TRUST and expect a safe flight each and every time, no exceptions....
