The effect is cumulative (the t4 builds up in your tissues) and while I do not take dessicated thyroid (I use cynoplus and cynomel), it was about 3-4 weeks before I felt any significant effect. It is important to go slow and monitor your temp and pulse as you increase your dose. You need to allow the body the time it needs to adjust.
My experience was I felt little to nothing and then all of sudden I felt terrific. Taking thyroid was the only thing that has raised my temps and has done me the most good.
This link isn't Peat but it explains in plain terms the danger of dosing too fast. Charlie can tell you about that as well. You don't want to do that because it will put more stress on your heart. The very last thing you want to do is create further stress on your body by taking too much thyroid hormone at once.
