Yeah, I've heard about this, and I wondered also. I've never had shrooms within a month of each other, but my dad told me that he went on a brief mushroom binge--"brief" meaning an 1/8 every day for five days. He said he felt euphoric but burnt out for about a week after, and in that period he couldn't count change very fast and stuff. But that got better for him after that week. And I should know, I've seen him at the crosswords and figuring out tax crap.
