Ask HN: Google Adwords Help?

Anyone know how to make Google Adwords spend more of my money faster? (without dramatically increasing max cpc). I keep waiting days for it to ramp up impressions and my daily budget is like 100x what it's spent so far. I did have it working well, but I maybe added some keywords and it dramatically slowed down in showing impressions on my ads. Also have it on search and display ads. Any Google Adwords experts?
