I have been having palpitations recently. I used to get them often when I abused vyvanse and adderol, but they diminished a week or so when I refused to take stimulants anymore (2 years ago). I have been working out for 3 months 5 days a week, but the palpitations have come back. I am only 24 years old, weigh 220lbs, and have no prior harmful medical history. I am 6 1 and in healthy shape. I understand I should get an ECG, but I can t afford the E.R. Bill. Lastly, I have frequent paranoia/anxiety induced by simply socializing with another individual. These side effects are more severe the more people I am around.
