I'm on a smaller dose (1/4 to 1/2 of a "full" dose) for the time being, so I only have a small idea of what changes I will experience. So far, though, I'm a bit more confident, and the quantity of irritation isn't changed. I notice that it sneaks up on me more, though. Before T, I would get angry slowly and gradually. Now, on T, it's a bit more sudden when it happens. I will jump from minor irritation right up to anger if annoyed long enough. But aside from that, the changes have been good. I feel more in control of my life, and control the speed and nature of my thoughts easier.
