Coffee makes you eat more?

Along with my dry January I also stopped coffee. The results are amazing, particularly on my sleep and energy. For the record I was drinking about 3-4 big mugs of coffee per day. Yesterday I took 2 mugs of decaf because I missed the taste. I felt exhausted in the evening, ate a huge pizza and slept poorly. Does caffeine makes you hungry later in the day? Just a coincidence? I guess my decaf had caffeine... GF brought chocolate as well, maybe it added up
