Does Suboxone make you sleep a lot?

Yes, Suboxone has drowsiness and sleepiness as a side effect.

Because Suboxone's adverse effects might be unpredictable, it's usually a good idea to have the drug's administration thoroughly monitored for at least a few weeks.

Subutex (buprenorphine) has a sedative effect. Drowsiness and sluggish reaction times are common side effects of Subutex, especially in the first few weeks of treatment. As a result, you should not drive, operate heavy machinery, or engage in other potentially hazardous activities until you know how the drug affects you.
