I have read a lot about people not being able to sleep b/c their laxative tea wakes them up or gives them cramps. I haven't had this problem at all. I think it's because of the one I picked up so I want to recommend it to everyone - Get Regular, Organic tea by Yogi Tea... it's a gentle herbal laxative w/great stuff in it. It tastes fabulous! Senna, anise, cardamom, ginger, peppermint, licorice, berries, dandelion and more. I haven't had any cramps from it and it definitely gives me bm's in the morning. It's only the beginning of day three for me.
