Caution
Both can dull each other's effects, so if one wears off before the other it's possible to overdose due to the lack of counteraction. Both substances affect the heart and may lead to further dangerous heart complications at higher dosages. Additionally, the combination may increase the negative side effects of each other.
The risk here is to the body — breathing, heart, temperature or organs. Set limits before you start, because this kind of harm does not announce itself in time to react.
