I used to always take kratom (an opioid) during psychedelic come-downs and sometimes during the come-up if I got too anxious. However, after I forced myself to work through these stages in several key trips, I discovered that the anxiety in both situations is psychosomatic. Now I dislike taking even kratom (which leaves the trip more intact than other opiates IMO) until the state is totally gone or I really need to sleep and there's residual stimulation, because I find the experience to be much more rewarding and complete when it is allowed to run to its natural end.
