So, near the end of december I had a very stressful day at work and felt a cyst coming (and I have gotten cysts over the years, like one or two every couple months), over the course of the next few months I kept getting cystic acne along my jawline and under it. I kept going back to the dermatologist to get them injected and slathering on topicals. I eat very healthy, exercise. I ate a paleo diet for awhile, never tried going vegetarian but food doesn't seem to have much of an affect on my skin so I began to think, my acne has been fairly consistant since 9th grade, when I started drinking coffee daily, cup in the morning and sometimes a cup after dinner. A month ago I decided to quit caffeinated coffee cold turkey and I rarely ever drink soda so that was my only real source of caffeine, I have been drinking green tea which still does have caffeine in it but since I stopped with the coffee I have not gotten a new cyst. It's not the dairy either cause I drink goat milk and used coconut milk creamer in my coffee or drank it black. So I can only attribute this to the fact that for me, too much caffeine = too much stress hormones = cystic acne! Just wanted to share this in case someone else wanted to try.
