This is the perpetrator of my yesterday's/today's misery. I must confess - I kinda did it to myself. I arrived in Cracow yesterday somewhere around 9PM, since I had nothing to eat in my apartment (I was returning after the holiday break) and all shops were closed due to the holiday I went for it and ordered cheeseburger and french fries. Then all I can remember is pure pain and misery.
One thing I am now certain of - much time will pass till I eat at McDonald's again.
