I've never reduced the Clobazam I take with Tegretol, but when we were
reducing the Tegretol (to add the Clobazam), it was done by reducing the
dose on alternate nights for a week,  then week 2 at the lower dose.   So
you'd take e.g. a regular tablet (10mg)  Clobazam one night, and half tablet
(5mg) the next for 7-8 days, Then take the second week at the half tablet
(5mg), level.  That gives your body longer to adapt to any changes.
   Also the pharmacist might be able to tell you, (or the Dr. if you talk
to them),  I don't use Aspirin (because of a blood factor I'm missing), but
was told to use Tylenol if I ever needed to .The Pharmacist has the scripts,
they might be able to tell you if Tylenol  (and which version) might work
better for you for headaches.   But the headaches might also be a sign that
the withdrawal is messing up your Blood Pressure? or something else, that's
causing those.  How's your Doctor about Phone consults?   G./
