Not that I recall, but I was surprised at the notable effects overall. Caffeine is so prevalent and people so knee-jerk defensive of it that we don't notice the powerful effects (be they good or bad). Unfortunately, it's been several years and I don't recall any specific reactions other than the sleep and that overall impression.
