I have constant feel to yawn to get deep breadth it's 24/7 feel and cos of this strain i have headache often and also pain under shoulder blade. Visited cardiologist neurologist and checked everything regarding but all of them said it's due to anxiety and prescribed tryptometer 10 mg in night and fludac 10 mg morning I just started taking three days before tell me what's my exact problem. I am little bit anxious too but I don't think it will affect this much my health.
