I’d love to hear how it worked for you! I’m sorry you have renal failure and congestive heart disease, my mom who is 51 has stage 5 renal failure and congestive heart disease as well, I just bought a cartridge with CBD vape oil and want her to try it. But she’s unsure so I’d really love to hear from you how it may have helped you. I hope things get better for you. I take care of my mom and know the daily stress and struggle it can bring. Again I’m sorry to hear you we’re diagnosed with those diseases.
