- 10%: dry mouth
- 2%: dry mouth, sleeplessness, constipation.

- one which lingers the longest.
- manageable by drinking water and chewing sugar-free gum.
Sleeplessness
- next most common side effect
- having a hard time falling asleep
- awakening early in morning and not being able to get back to sleep.
