I have year-round allergies that require me to take an allergy pill almost daily. When I go to the pharmacy to buy allergy medication, I'm required to sign a disclosure statement and submit my driver's license. I'm allowed only so many pills per month. If my allergies are bad enough that I require more medication than the law allows, I must go to a doctor and get a prescription. These monthly allowances are carefully scrutinized. I've even had to return one day later to be allowed to obtain the pills because my monthly allocation has been used up and I'm not eligible to get any more until the following day (the start of new month).
