Only used it one time. Took around 200mcg intranasally and ended up talking nonstop to my friends in a cheerful way.
Tried this over the past few evenings and planning to again tonight. The main thing I notice right away is a strong flushing, like my face getting hot for a few minutes. Beyond that it's tough to pin down any clear effects, though occasionally something subtle shows up. Has anyone gotten positive results, and at what dose?
