If your going to use benadryl then you don't need to take two weeks off. You could go 2 weeks on and 1 week off. Use benadryl the third week and use one capsule 25 mgs. On the fourth week just pick the clen cycle back up and you should be fine. Make sure to take taurine daily throughout the cycle. And yes the benadryl method worked better for me, than the two week on two weeks off method. But with clen everyone is different, good luck.
