Hi - I had all of the side effects, significantly, when I first started. I just hit my one month mark now with Tymlos. The game changer was thanks to a post by @ windy shores who indicated she did not use the full dose of 80 mcg. I no longer do the full dose and stop a click (sometimes 2) just shy of seeing the 80 in the pen window. I still have mild side effects like faster (but not rapid) heartrate and my worst side effect is that it makes me feel a bit woozy and tired. I'm going to stick with the lower dosage because it's better than nothing! I did tell my doctor what I was doing and she was fine with it. Give it a try and best of luck to you.
