Digestive issues are a sign your body is warning you. That is my lightbulb moment. When I started feeling sick every morning.....its time to stop and get help. It's never too late. Scoot on over to your gp and let them know the situation, honestly. They will know the right course of action for you.
I'm with you. I'm literally on day 1 and failing miserably. It's effing hard. But please listen to your body. It's saying hey! Stop it please.
