Right now I only have a cup of coffee per day. It is always in the morning as part of my routine or if I train early I have it with my preworkout meal. Eggs, oatmeal, and a cup of black coffee. Here is a great way to lower caffeine intake without getting headaches......
Make your own coffee at home. Mix 2 scoops regular coffee and 1 scoop decaf for 2 weeks. Then do 1 scoop regular and 2 scoops decaf for 2 weeks. Then you are good to go. I guarantee that after this you will not "need" a morning coffee just to avoid a caffeine headache. Decaf still has a super low amount of caffeine so your body still recognizes it. That and with it still tasting the same and being a hot beverage it tricks the body as well.
