Try hourly vacuums. If that doesn't stem the tide, make it more often
(or try autovacuum). Also make sure that your FSM settings are large
enough; if they're not then no amount of plain vacuuming will keep you
out of trouble.
With sufficiently frequent plain vacuums you really shouldn't need
vacuum full at all.
I can't recommend an analyze frequency on what you've told us.
