You wouldn't feel it after the first couple of weeks, it takes about 2 weeks for 25b's tolerance to return to baseline. You'd just be getting sense enhancement, mild euphoria, and stimulation for most of the 2 months.
i did 200-250 hits in a month and am fine, i wouldn't worry about once a week for two months. of course that's just me, you could go insane or something i guess.
