You wouldn’t believe what severe acid reflux will do to you! I had many symptoms like this when my doctor told me to change the way I eat. I laughed out loud, because there was no way it could wreak such havoc. I was not a heartburn sufferer, and walked miles every day. Until I couldn’t! It also causes fatigue. Research an alkaline diet, then cut back on the foods contributing to your symptoms. There are several books out there to help you. You will be amazed!
