I had medication-induced insomnia a few years ago due to some drugs I was on for another condition. It was horrible, I was so tired but wide awake and couldn't fall asleep. I would go multiple nights with zero sleep and my mind wouldn't function. I wouldn't even get close to sleeping. The doctors had to give me antipsychotics to get me to sleep since I wouldn't even react to sleeping pills. I did learn a lot about myself and I now have amazing sleep hygiene. I don't do math or programming before bed but I will read books on the topics. Anything that makes me think too hard is gone. I've actually shifted my sleep routine to 8pm-4am so I can wake early and do programming.
