Hi , I'm starting a Water Fast in two weeks time. I would like to do the fast for 21 days followed by refeeding for at least 10 days. Over the last 4 weeks I have cut out meat, dairy and wheat based foods. This week I am eating fruit, vegetables and drinking coconut milk. I use organic where possible. I have a history of metastatic melanoma and thyroid cancer. My thyroid gland has been removed and I take thyroxine every day to replace that which my body can no longer produce. My concern is that I've read in some posts not to take any meds but I think the thyroxine is essential? Does this mean it's not safe for me to do a Water Fast for 21 days? What about other supplements such as magnesium, sodium and potassium? Can the body store these minerals? Should I 'top up' my reserves before the fast? Apologies for the list of questions! Any advice would be greatly appreciated. Thank you
