I've been prescribed to this for a UTI. I've been taking it for almost a week now, Monday is my last dosage. I'm an athlete, I run and lift heavy. When the doc prescribed it be said no lifting heavy. I haven't worked out since started taking it. Can I start running and lifting again now or when I take my last dose? I'm feeling like 💩 since I haven't been working out. Any information would be great! Thanks a bunch
