Caffeine is much more similar to Amphetamines–which actually aren't that dissimilar, chemically. That includes wakefulness and positive mood, but also nervousness, rapid heartbeat, irritability etc. Ever worked through a night drinking energy drinks (the sugar helps) and been wide awake the next day? That's how amphetamines feel. LSD is actually a much more relaxed experience. It's like working on something you really enjoy, on a sunny afternoon with no deadlines in sight, listening to jazz and sipping an iced cappuccino.
