Need Help

My chronic constipation has gotten worse and I have no appetite which means I am losing weight. There is a Jamba? Juice store that sells wheatgrass. Does anyone know if it would help with constipation and if you can mix it with fresh carrot juice? I have to take Senokot or Miralax to have a bm. I can't see a GI doctor till Thursday and I sure would appreciate any comments. Tweet
