I noticed that for the last several weeks, the facebook commercials to watch for boosters/rests/treatments/money (Facebook in-game currency API) have practically disappeared, and in those few cases when they showed up for me, once in several days, they did not credit anything anyways. Rests, treatments and money have other ways of replenishment, but boosters don't, with the exception of winning 1 per game, which is very far from enough. So I wonder, what do you guys do - spend the tokens?
