First off, you shouldn't have to use three mg tablets.  They do come in
1 mg.  Not quite as easy to find, but I live in the middle of nowhere on
the reservation and my local Walgreens carries them.  Natrol makes them,
as does Nature's Bounty, I blieve.  About once a month or so, they go on
sale for two for one.  I think someone told me CVS also has them.  So
much easier.  I used to use liquid melatonin which I bought off Ebay.
The only other places I've seen them are those big health food
supermarkets.  I can't remember who makes it--two companies.  One is
something like sunrise?  sundown?  something like that.  They're quite
a bit more expensive than the tablets and usually formulated with some
glycerin and flavoring, if I remember correctly.  So they're kinda sweet,
which might be a problem if your guys have insulinoma issues.  But try
ebay (search liquid melatonin) or a big health food store.  Or just get
1 mg tablets.
