I have been taking Amitryptiline for about 5 or 6 weeks while I taper off Clonazepam but the Dr. Started me on 25mg and then 50mg and Bumped me up to 100mg and 9 days into 100mg my blood pressure and pulse rate spiked so I went to the Dr and he said to cut it in half so 2 days later my blood pressure and heart rate spiked again. When I checked it, it was 137/90 and heart rate was 120. I and going to cut back slowly and come off of it. I am feeling a little off. I don't like it. Scary.
