Edit: maybe this communicates it better to some people - bipolar is a tail risk of sleep deprivation / experimentation with sleep schedules / etc. It is low-probability.
But not fucking with your sleep is "antifragile". If you agree with Taleb generally, you won't risk it. The downsides are immense. You can easily spend all your savings in one weekend buying soviet filmmaking gear. And that's just the financial side. Bipolar is treatable but doesn't go away. It's just easier to handle. You go to the grave with your pillbox in hand, just in case they buried you alive.
The minor disruption of having to take a handful of pills every night, 3 minutes times 365 days times 35 years = 2100 hours. You could probably learn French, German and Italian in that time. I'm refraining from talking about the major downsides. Educate yourself.

You can also have a latent allergy to peanuts but you always ate small portions. Then someone says "eat only peanuts for a week" and someone says "beware, some allergies are cumulative-exposure, you could be especially sensitive". Then you weigh your risks and benefits. Maybe have someone around to help you if you choke.
With bipolar you won't know what's happening right away. It will seem you're having the best period of your life (and you are!). Weigh your risks and benefits. What's being proposed is a lifehack. You could also try to sleep right the way your mother taught you to.
