Does yohimbine's fat burning effects work with continued use?

[rawhide]

I've read conflicting reports regarding yombine's fat burning effects. Apparently it's noradrenaline stimulating effects wear off after 14 days continued use (ref1). Most guides recommend cycling it, but I have read other reports of extended use of more than a year with good effects. I always take it fasted before working out. I've noticed the side effects have become almost non-existent even at very high doses like 20mg 2x a day. On the contrary it give me a very positive mood lifting effect which I would enjoy even without the fat burning effects. I am concerned about becoming dependent on it.
