certanly the "feeling" diminishes. on each run it seems quicker to do so also. however, its fat burning effects do not seem to do so. in fact, just the opposite. but, that could be because by that point im taking 2 scoops 2x a day...and even a little more sometimes. Dont believe ive gone over 6 in any one day yet. But, you also burn through the product quickly at that rate.
i think most ive run continuous is 4 tubs probably around 11/12 weeks id guess.
