bronkaid + caffeine pills....you can get them from Walgreen's or Target, a months worth for around $25.
I was just talking to the pharmacist that sold me the last box I bought, and I mentioned that I remember when the Bronkaid was $7.99. Not it's $14-15 a box. Double the price in under two years time. The pharmacist remarked that with every new batch, the makers seem to jack the price up just a bit, for whatever reason.
