suggests taking the 2 hydrocodones you have and mix with 2 tramadols.
If this does not increase the effect enough up the dose to 3 tramadols.
Do not exceed 3 tramadols(at least i dont. Heavy abuse of tramadol
can lead to seizures so SWIM tries not to abuse tramadol too heavily)
If you are still not getting the desired effect mix the 2 hydrocodones, 1 tramadol, 1 flexeril.
Up the dosage from there with the tramadols if you are not getting the effect desired.
Again..only go to 3 tramadols.
In the end i would not exceed 2 hydrocodones, 3 tramadols, and a flexeril.
I personally Hate flexeril so i wouldnt mess with it but if it is good for you Go For It.
