Have you seen a doctor about it? Doctors are usually useless about sleep issues, but a sudden change is more likely to have a cause that can be pinpointed (e.g. pituitary issues as mentioned elsewhere, maybe adrenal issue). Also, seizures that only happen at night are apparently somewhat common and can disrupt sleep. Even narcolepsy of all things can appear as sleep disruption. If you did try to see a doctor and got brushed off, maybe try again. In my experience phenibut is the strongest medication easily available for staying asleep at night, although I switched to 10mg baclofen that is somewhat less effective than 600mg phenibut for me but I feel more confident about the safety and it is less addictive. At one point I took 600mg phenibut one day, 10mg baclofen the next, and nothing the third then repeat and that seems to work well for at least a month (I also recently tried taking baclofen for a few weeks at a time and while it didn't do much after a few days I'm fairly sure it did still do something, although I worry about using anticholinergic medication so frequently). Magnesium (600mg before bed) helps me as much as phenibut but wipes me out even more than usual the next day. I also use 150mg uridine monophosphate sublingually a few hours before bed, which doesn't help much with staying asleep but helps me feel more rested (nootropics depot is the highest quality source of the powder I have been able to find). That works best taking a few days off every month and a few weeks off every year. But I think in your case trying to figure out the cause is likely to be the most effective thing to try at this point.
