I’m staying clear of all meds now, cos of bad side effects plus that wd interfere with the acupressure that is working. Just trying some last supps and herbs (partly again). So I’m not that firm with the meds that are recommended in the UK & US (not here in Germany) yet, altho I’ve read tons of studies and experiences.
The reference-thread I’ve just started building up might help you if you’re looking for a list & description of “everything”, but it’s just pecking open its shell.

My best treatments are a bit of a challenge for even those that think they would really try everything: Cryotherapy and cold-showering (which I did try altho I feared - like probably everyone - the cold’d be bad for me, like cold weather is). So I don’t share these as much as I first did… These actually are 2 things I use to get the flu-like Ache and feverishness down. But also sleep. Which is my biggest problem. GABA may be helping tho…
