I'm 38 and I always feel slugish, I lack energy and just want to sleep all day if I don't drink coffee or take a pill like presciption diet pills. Since I was 27, I've relied on diet pills and coffee to have energy. I've tried many times to do without coffee or pills but all I want to do is sleep and lay around. I have a very physical job, cleaning houses. What is wrong with me? I look at others and wonder how they do it naturally and why I struggle. Please help!!
