When my son did EEN for six weeks to induce [wiki2="Remission"]remission[/wiki2], he was allowed clear fluids. This included clear pop or gaterade, freezies/popsicles (no chocolate), gummies, clear candies (again, no chocolate flavour, caramel, etc.... only 'clear'), jello and broth. The broth made a big difference! Being able to have a bowl of broth as 'dinner' gave him something savoury. As well, he was able to take broth to school in a thermos and eat lunch with his friends (I know school is ending but this could be done when going to a friend's for the day??). And, while limited, there is some variety in broth - beef, chicken, veg, seafood. (I bought organic broth - the one I made at home never seemed to be as clear as the store bought.)
Perhaps ask your son's GI if he will allow clear liquids along with the EEN??
