Hi @jovigrace, I can see you're concerned about the rapid weight gain and other side effects from metroprolol. I think you'll find this article from Mayo Clinic informative:
- Beta blockers: Do they cause weight gain? https://www.mayoclinic.org/diseases-conditions/high-blood-pressure/expert-answers/beta-blockers/faq-20058385

Have you talked to your cardiologist about the weight gain? It is important to distinguish whether this in normal and expected weight gain or possibly problematic like buildup of fluid. It might be a medical issue or perhaps a different beta blocker would work better for you. How long have you been taking metroprolol?
