hi D. nice to meet you. what is CFS may i ask. welcome to psych central. i struggle with some of the same issues. i have very low energy, get sick a lot, have depression, DID, athritis, fibromyalgia, asthma and very low energy. i'm on a lot of meds too which i think might be causing some of the low energy. strangely enough i have been craving lemon in water too like our above friend. do know you'll find much friendship, love and support here. wish i knew how to get you more energy because then i would have it too. wishing you the best. may angels surround you.
