All these drugs are not good for you [especially the benzo's (Xanax) and
hydrocodone (Norco), and especially if taken long term].  Your doctor is a
fool (IMO) to keep prescribing those long term.  You will build up a
tolerance and become a friggen Junky, and get serious withdrawal if you try
to stop them suddenly without weaning off.  The Lexapro and Atenolol can
also have withdrawal problems if discontinued abruptly, but at least are
more conducive to longer term use, and of course are taken for different
reasons, and may be more necessary to treat your condition.

That is a lot of stuff to be taking all at once IMO.  I am not a doctor, but
I have seen many times that doctors don't even know what's in the package
insert for the drugs they prescribe or have never read the package inserts
for the drugs they describe, and at best they go by what the PDR says, or
what the sales rep said (who drops the samples off at their doorstep) - and
of course they have their favorites that they still use from their med
school and residency training.  Best wishes...Pete
