I'm almost always even-tempered, although from time to time I enjoy a good rant. But I gave up Tren after I jumped on top of a jerk's radio, crushed it totally. Combat boots and 250 lbs didn't leave much. Surprised a lot of people, including me.

If you can do without the one or two things in particular that aggravate your mood, just avoid it. Otherwise, learn and practice some sort of relaxation technique. TM works for me.
