I've been juicing for 2 months, now for the past 4 days i haven't had a complete solid bowel movement. could something be wrong? thanks

Probably not: If you are juicing and not eating solid food, you will not have daily bowel movements. Juicing is a way to get concentrated plant nutrients but there aren't many solids in juice. It wouldn't surprise me at all if your bowel movements were farther apart. I would only worry if your abdomen became distended and you started having abdominal pain. Otherwise, sounds normal for juicing Best wishes
