Hey Zeds, I'm glad to hear your anxiety meds are working and have been working. Also, I'm glad to hear your ECG results are normal. I am bothered that your meds have now stopped working? and doubled? I think there is another factor in play. (undisclosed?) Most doctors would address fatigue and headaches and muscle pain as separate problems, but may increase meds due to increased anxiety. Keep in mind that anxiety is high for many around this time of year. Me, personally, I feel like a grinch. Do you want to change your meds at this time?? The nervousness may be due to other things going on in your life and, may pass in time. Id say, take what you need and leave what you don't. Focus on your health and try to get through the holiday season before reevaluating your symptoms. Time itself is surprisingly healing :0)
