Does anyone else have acid reflux? I was just diagnosed and am wondering if one of the side effects could be horrible fatigue. I have had symptoms of reflux for more than 20 years, but just thought it was allergies. It seems that all the mucus and sinus drainage is caused by acid reflux. I am about to start a regimen of medicines and change in diet. My fatigue is unrelenting. No matter how well I think I sleep I am always exhausted. I have sleep apnea and use a cpap at night but it doesn't help the dibilitating fatigue. Also diagnosed with fibromyalgia years ago. I hope someone can help me.
