Have you been getting enough calories and carbs? Adding more bread helped me somewhat with similar tiredness from tirz before. Electrolytes are another frequent recommendation, whether from drinks, certain foods, or even protein shakes.
Is anyone else dealing with really bad tiredness while taking Reta? I've been on it roughly four months now and at 5mg for the last six weeks. I'm exhausted constantly. Even with eight hours of sleep I still end up needing a three-hour nap on weekends. I'm nearly nodding off at my job and it's driving me crazy. Any peptides that might help fight this kind of fatigue?
