Don't take speed.. it's illegal and it ain't that safe. If you are set on taking drugs to study, it's probably safer to take Adderall or Ritalin, which are prescribed to people with ADHD. For people without ADHD, it causes them to be able to focus on a task for long periods of time.

If you are going to stay up all night, try coffee. If you don't already drink it daily and have built up a tolerance to caffeine, it should be easier to stay up.. I've tried caffeine powders, but I ended up getting headaches that made it even harder to study. Maybe it might work for you.
