Trying to lose a bit of weight, I substituted my evening meal with a plate of raw veg - carrots, celery, broccoli and cucumber - and humus. At 3am I woke up with excrutiating chest pain which travelled to my upper back. It subsided after I made and sipped a mint tea. That was four nights ago, nothing since, but now I'm worried it could be a warning of a heart attack! Am I panicking unnecessarily?
