Thanks to all who replied to my request!  I really appreciated it.  Here are
the responses I received:

I KNOW that all Robitussin products are GF.  Sorry, I am not sure if they
have a nighttime cold medicine, but if I were at Harrah's, I would put my
money on 'yes'.  Good luck.

I called Whitehall-Robins on 10/4/01 (800-322-3129) and requested their
current GF list.  The following Robitussin cold medicines were on their
list (the list was dated Aug 2001):

   Robitussin Cold (Cold & Cough Liqui-Gels)
   Robitussin Cold (Cold, Cough & Flu Liqui-Gels)
   Robitussin Cold (Night-Time Liqui-Gels)
   Robitussin Cold (Severe Congestion Liqui-Gels)
   Robitussin Cold (Cold & Congestion) Caplet
   Robitussin Multi Symptom Cold & Flu Caplets

You can go to www.clanthompson.com ; they have a list of OTC and RX meds
that are gluten free.  They have other great info also.

Nyquil is gluten free.

Chlortrimetron 8 hour is an antihistamine that is GF.
