What do you recommend for drooling?

Depends on the cause. Some medications cause drooling. The easiest solution is: sugar-free gum or candy. This doesn't fix the problem but encourages you to swallow often, so drooling is less of a problem. Another solution some doctors use is atrovent nasal spray, sprayed under the tongue. Anticholinergic medications are sometimes helpful too.
