Mixing Caffeine and DXM (robo)
Caution
A lot of caffeine can make a dissociative trip more anxious and uncomfortable. Keep caffeine light.
High doses of caffeine can potentially exacerbate anxiety, especially during a dissociative experience, due to its stimulating effects. This combination might also lead to physical discomfort. However, individual responses to caffeine can vary significantly, often influenced by factors like habitual versus occasional usage.
The risk here is to the experience — intensity, panic, thought loops, confusion. Physical harm is unlikely at ordinary doses. Setting, company and dose do most of the work.
