I'm in the same boat. What I do though is keep a moustache comb in my pocket and every so often, I'll duck into a nearby restroom to give not only the 'stache a tidying up but the beard as well.

I've joked with members here in the chat that as my beard gets longer, I'm gonna have to get a utility belt to keep it looking its' best.

Stick with it though. Don't let the increasing amount of grooming keep you from growing and showing!
