I was the same. Liked it sharp at all times. Would try to go every week, never more than 2 weeks. But I got fed up of waiting for an hour for a haircut so just went 1 all over and did it myself.
Got bored of that and learnt to do my own hair with a simple short on top spiked up buzzcut thing. I've decided to grow it out a bit and have a slightly more adventurous style now. So I guess it's back to waiting at barbers for me.
