Normally if I have a lot of work to do (at university) I will have a strong cup of coffee or very occasionally take amphetamine about ten minutes before I start working. However I often feel I havn't "woken up" enough until a good few hours after waking. Would consuming caffeine and/or amphetamine as soon as I woke up mean I would be more alert an hour or so later than if I merely timed it so that the full effects would kick in just before I started.
