I had the same problem when I started wearing contacts a few years ago. Drops helped but were obviously inconvenient. Eventually I got so worked up over the problem that I became extremely aware of even mild dryness and very bothered by it, and I started blinking more often. Problem solved and hasn't bothered me since. So... perhaps this is dangerous advice... but you could try becoming hypersensitive and obsessed about dryness.
