Just out of curiosity now, I plan to ask the pharmacist at Walmart (they know me well) how many scripts of Plaquenil a month they fill. We are not in a large city, so I would guess very few, but nonetheless, I will ask.

I have to keep in mind, those that go to a forum are usually people with more advanced conditions...as for why there might be a higher percentage of Plaquenil users on the forum. Those with just mild symptoms of dry eyes/mouth are likely not seeking support from a forum.
