I posted on here before about this but I started this Monday for my high heart rate and my cardiologist only wants me on it for a week and to see how I’m doing after that . Has anyone only been prescribed this for a week ? He said if it’s still racing all the time I can continue but to stop after a week and see if it’s better . It’s for my anxiety which I’m increasing my meds soon . 

Also I read about weight gain with this can this happen at this low dose ?
