@greenshade I would try another doctor if they would not let you continue low dose naltrexone. Lots of long covid folk have been on it for over 1 year and I am approaching two. There are tons of studies showing its safety and its good effects on long covid symptoms.

I also could not do keto/low carb initially with the long covid symptoms. After 6 months on naltrexone, I am much more successful and only have a cheat day every few weeks. And boy does the next day hurt!!!
