Heart Rate Question?

I was hoping to get some opinions, I have posted on this site several times with no luck and was hoping I could get some advice this time around.

I am currently doing the advocare cleanse stage and today was day 1. Got up and took my vitamins and had a good breakfeast then went to go workout. I guess my question is , is I was wondering at what point a resting heart rate becomes dangerous?

I am prescribed 70mg vyvanse which is a stimulant to help as apart of my total treatment plan. Took it at around 8:40 and looked at my apple watch at around 11:15 and noticed my resting heart rate was 110-120. Normally without medication it is alot lower as in between 80-90. I know vyvanse is a stimulant but I know my heart rate seems to be pretty high for it to be resting. The only thing I can think of is that in the morning I take advocare spark. Has 120mg of caffeing. I had that at 5 :30 and then didn't take my medication until 8:40. So I really do not think that was the issue . But then again I don't know. I am trying to get healthy , and am sick of having to take 3 mg of klonopin to calm down like I had to throughout the day.

I am going to see my doctor next week. I am going back and forth as to whether I even want to wear my apple watch during the day when I check it constantly.

I had mentioned this in a previous post , and this may not be the time and place to discuss this, but I have always wondered with ADD/ADHD has not been a forum on this website. I feel that there are other individuals who would appreciate that.

Thanks for your time

This was just day 1 . I didn't feel anything out of the ordinary at all. Just happened to look down and see my heart rate was elevated.
