I tried this once and it didnt work.
I think I ate too many strips 
Even if you took too much, you'd still feel all fucked up. There's a "sweet spot" that you can overshoot, and if you do that, the effects won't be as intense as if you took the right amount. That said, it would take A LOT to overshoot it, and if you were trying this with strips, it's much more likely that you did not take enough.
From what I understand, the timing is tricky with the strips. With syrup, you know you have 30-60 minutes before you get off. With liquid caps, you have between 1 and 2 hours. Strips contain much lower doses; iirc, you would need (I think) 2-3 full packages to get any effects, much less hit the sweet spot. Not only that, but due to the nature of the delivery, I am not sure how much time you have with strips before effects kick in. I don't know how to predict the metabolization there.
