I have been on Phen for about 2 weeks. About every other day I feel like I can't catch my breath. Like I can't take a deep breath. Is this normal, anyone else feel like this? It's a horrible feeling and I'm not sure if I should quit. I have had no other side effects and would be bummed to stop because it's working, not sure what to do, any advice would be greatly appreciated.
