I don't think the enhanced creativity is a figment of your imagination. It certainly does that for me, as well as getting me to think in different ways. The reduced productivity can definitely be a thing. I have it dialed in pretty well. With 5mg I don't feel that "hang over" lethargy in the morning but still experience the benefits. Lol, maybe you should try a good Sativa. I've sworn it off since I mistakenly took 100mg in Montreal a few years ago.
