This drugs are incredibly addictive and VERY an easy task to increase tolerance. It was worthwhile when I was organized, cannot move due to back spasm as well as in incredible pain. It allowed me to go slowly and gently, perform gentle stretches and straightforward movements for healing. However, with sufficient dosage, in addition, it posseses an incredibly relaxed feeling, as if all worries are gone and life is an attractive, often funny experience, packed with love. This feeling needs a higher and better dose to realize. And comes with negative effects like dizziness, sleepiness, lack of motor control. Side effects rise in intensity with increasing dosage to the point of total inability to go limbs and dropping into unconsciousness.
