Yes thank you so much for your suggestions. I make smoothies with veggies and protein powder in the morning but need something I can take with me. The Atkins shake is a great suggestion. I dont have a GI doctor right now. Had one years ago but werent very helpful with IBS. Im trying a new drug called Constella for Chronic Idiopathic Constipation but maybe the barium test is a good idea. Thank you for taking the time to reply.
