Hi Jack, I'm so sorry to hear that your advisor is being incredibly and unreasonably demanding to you. In my personal opinion, the way your advisor behaves is absolutely not normal (although I won't be surprised if there are a few like him in the academia). You might be able to respond to his demand for now, but after a while, this whole thing can really wear you out physically and mentally (I can barely work above 12 hours a day and absolutely not on regular basis). In a long term, I can't see how this works out. Since you are very early in your PhD career, I think it might be better for you to start looking for another advisor who is more reasonable and respectful. That is, unless you, for some reasons, really need to work with this advisor (i.e. he is the only person in the field).
