Breastfeeding and weight loss

We’re almost to 15 months of breastfeeding with my little guy and I’m ready to kick this baby weight. The only problem is, I’m sooo hungry all the time, and I’m exhausted after a long day at work and chasing a small toddler. I can’t keep chugging coffee and stuffing my face 24/7 🤣

Pre-baby, I took garcinia cambogia and I LOVED it, but it hasn’t been studied for breastfeeding safety. Has anyone gotten the okay from their dr to take GC? Are there any similar bf friendly weight loss or appetite suppressant/energy boosters?
