Joe takes Nortrip 35 mg a day which helps his headaches a bit. He is going to a new headache specialist now here in Virginia and told the doctor about his high pulse and high anxiety, especially in the morning. The Doctor said Nortrip definitely increases your heart rate. He advised moving the dosing of Nortrip farther away from bedtime, and adding Propranolol to slow down the heart rate. After 3 weeks on propranolol, his heart rate is a bit slower although still too high. He still has anxiety, especially in the morning. Headaches are less severe in the morning, and get worse as the day goes on. This is his Mom Julia typing since he is still not using the computer.....

I was exactly the same, fast resting pulse and waking up in the night with heart racing and in my case sweats, thankfully this didn't happen every night. I reckon light exercise in the form of walking and the deep breathing exercise @underwater mentions helped me since 4 3/4 months in it's gone. I also cut down caffeine and reduced my sugar intake too. The high pulse seemed to be part of the anxiety symptom (the signature of PCS!). It's like I had to retrain my body to increase and decrease my pulse according to physical demand because it had got stuck lol.
