Waking up naseous

One thing I hate about systemic lupus, is the constant fatigue. I may sleep even the whole day but still wake up restless and seem like I haven't had enough sleep. What I hate most is waking up completely nauseous and groggy. I took prednisone yesterday (I actually cheat on my medication because I would hate it if I get really fat again.) And today I woke up so dizzy and my back is aching. Things I normally get through with the disease. I envy normal people and I do miss my healthy days.
