Managing Tolerance?

I've just started buying my own weed and therefore have new control over when I smoke. Now at first one tiny cone (aka bowl) would get me baked, after about a week of daily use it would take about 4 cones to get to the same spot.

So, my question for you ents is how do you manage your tolerance, does it even cross your mind? Do you put yourself on a strict regime or do you just go with the flow and pay no attention?
