This is a very common combination,
and I think
you mean 2.5 mg of
xanax. I would ask your doctor about increasing the Paxil if it has worked for you these last two years, or switching to one of the many other antidepressants. I would try to avoid increasing the dose of xanax, and possibly ask about switching off xanax to klonopin. You might also consider therapy to look at the source, rather than the symptoms.
