It is a standard practice in *all* state hospitals in China by which
anyone who is diagnosed of having had tinnitus is given intravenous
injection of various kinds of medicine.  The doctors in China do that
only because they have seen enough cause-and-effect relationship
between blood circulation of the head on the one hand and tinnitus on
the other.

So it is fine that you are on drugs and doing habituation.  But don't
just stop that.  Go one step forward to have your tinnitus better
treated or even cured using other means.  It is *said to be* easier to
recover for new T sufferers than for the old but nothing says old T
sufferers are unable to recover or at least have their situation
improved with prolonged intravenous injection treatment. Go for it as
long as the consequences are reversible and the consequences are
reversible.

Good luck,
