Do To many sleeping pills and pain pills cause facial expressions?

They shouldn't cause strange expressions when you first take them - if anything they would reduce your expressiveness.

However, if you take them regularly, then stop taking them, you are likely to go into withdrawal. Withdrawal from either of these medications (especially sleeping pills) can cause twitching and seizures. If you're having facial tics and feeling rather sick, you've probably been taking the medications too often and are suffering the consequences.
