Have you tried a vitamin A supplement? I read in Taking Charge of Your Fertility that Vitamin A helps in mucus production. I take 5000 IU a day (my prenatal has no Vitamin A - I believe the upper limit is 12000 IU to avoid toxicity). I've noticed a big difference - and fairly quickly. Last cycle I took it sporadically and noticed that my fluid wasn't as plentiful. It really makes a difference for me.
