Tinnitus - do you have ringing in the ears?

Pbb actually your recent rant does nothing to clarify your incorrect position regarding the difference between efedrine and efedra. Your statement is like asking audioengineer to clarify the differences between interconnects--i.e. completely invalid.

Is it a coincidence that your user name starts with pb which is the sign for lead (a dense and toxic material)on the periodic table of elements?

Anarchy, you are precious, ad hominem and all.

Once again a complete avoidance of the issue and the truth.

Hey, this is a perfect example of why I did what I did above. What Pbb needs is a shot of testosterone. The estrogen comes through loud and clear. Or, is this a Canadian malady?

Protect your hearing, use earplugs and ear protectors, limit exposure to loud sounds such as power tools (this apples to everyone). I've has tinnitus about 20 years, it started as a result of falling asleep listening to headphones, woke up with it. Tinnitus can start with one exposure to loud sounds, protect your hearing, tinnitus can be pretty nasty (I know first hand) and it's a lot easier to protect your hearing than have to deal with the damage after the fact.
