(F17) i took my first does of it today. i’m told to take it 3 times a day.  i was prescribed it for my tachycardia and pots. i’ve heard it also helps anxiety??? i have had severe anxiety for years and panic attacks for years. i took my first shower today without needing to sit down or pause because of my heart. my resting hr is usually 70 to 80 bpm but now it’s 60 to 70 bpm. i can tell the tablet is working but my anxiety thinks it’s bad that it’s fixing me?? like my heart needs to race and beat to help my body function and the tablet is hindering it from helping me. if that makes sence lol but i feel like this is going to put me into a heart attack or kill me. i have always gotten random chest pains and i’m still getting them today. idk what going on maybe it’s all in my head.
