Knowledge can do that In my favorite movie "MATRIX", Neo started learning knowledge (symbolized by the kung Fu he was learning) and stated "I WANT MORE!"
Just be careful not to lose your balance, the God says to beware of excesses. The God says to be patient and take your time with things. Make sure you give your physical vehicle the proper amount of sleep.
Other than that , there will be times when you stay up all night studying and pondering, that is normal for a seeker of truth.
Regarding addictions, if there is something you wan to stop, you must IGNORE the thoughts that come into your head about it. You can only focus on one thought at a time, so have some alternative thoughts ready, there are plenty thoughts in the reading(quran) thatcan replace the thoughts that come from addictions.
