Ha ha! So... There's another option. I started LDN almost 2 weeks ago (.5 mg) and after using it for 6 days, these symptoms kicked in. According to my doctor (and the LDN research trust guidelines) it is quite common for ME/CFS patients to develop flu like symptoms initially (probably indicates the dose is too high or LDN doesn't work for them). My doctor told me to stop LDN for 2 weeks and then start again on a way lower dose.
I'm convinced now it's not a virus because there has been zero change over the course of the week. I'm just absolutely knackered and can't stop sleeping. Housebound, which I haven't been before.
I hope that, after this update you can breathe again,
