Remember the commercial “Maybe it's your coffee”? Lay off the caffeine- if you can eliminate gluten, you can lay off stimulants. You are trying to squeeze blood from a stone.
Apart from what you have eliminated, are you eating well? Plenty of fresh fruits and veggies? I have taken “raw adrenal” (bovine derived) for short periods of time, with good results. Lay off the coffee and drugs. Get plenty of sleep- caffeine can affect you long after you think it does.
