I have the same problem, meds wearing off I mean. I've found that spacing them out so my last dose (200mg of the 300 daily dose) is taken about 6 hours before bed. I still feel the impulsively and restlessness come back within that time, but any later and the meds keep me up all night.

To help me sleep, I keep a fan running all night, and it works like a white noise machine. Also, how long before sleep is your last meal? Eating too close to bedtime can have hugely negative effects on your sleep quality. Looking into your diet overall is a good idea. Since becoming vegan (7 years ago) and doing daily intermittent fasting (1 year ago), my energy, weight, and overall health have improved exponentially. Something to consider. As far as the main issue of impulsively, restlessness, and reckless behavior, I wish I could help but I'm still trying to find a solution myself. Best of luck to both of us I guess.
