Hi Rachie:

I had to give up coffee quite a while ago. I know about feeling foggy and lethargic at times. This may be a dumb idea, but it works for me - I use headphones (at work) and sometimes listen to music. For me, it's mainly rock and pop, but it could be any kind of music. Just an idea.... That and deep breathing sometimes helps. But a great song can do wonders.
