Found this through search years later and it is still the best discussion of the question, so adding one thing. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.
Worth separating that from the titration schedule, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.
