I have been on Claritin-D for probably 5 years now, at the suggestion
of my doctor for frequent headaches and dizziness.  It seemed to work
very well, but after that many years of being on it, I decided I wanted
to see if I could find a better way other than drugs.  I bought the
Grossan irrigation system and I do like it, so I stopped taking the
Claritin-D.  I managed to go one week without it, but am SO TIRED I can
barely function at work!   I crawl home from the office and curl up on
the couch and still don't feel rested after a nap.  Out of curiosity, I
took a Claritin-D last night and woke up this morning feeling like my
old, alert, wide awake self again.  My question is:  is there a drug in
the pill that is doing this to me, or is it the simple fact of not
being congested/swollen that makes me feel better?  For example, was it
the lack of drug that caused me to want to sleep all week, or was it
the blocked up head that made me so drowsy?????

Thanks in advance - I don't want to take Claritin-D if I'm simply
addicted to the drug - I want to know it's because it's doing it's job
that I feel better.
