I'm giving it a shot right now, My symptoms are similar to yours. I'll let you know if it helps, I think on the reddit CFS/Fibro some people report big improvements, while others report nothing. my symptoms are kind of similiar to you, where I was diagnosed with CFS/ME due to the primary neuro symptoms (weakness/tingling/myoclonus) but i came to realize later after abstaining for a while I was deep in to a continual POIS flare up and when I abstain it improves significantly, but it can take a while like 4 weeks to recover. If i had to guess brain stem has some degenerative changes that makes it super vulnerable and then when you pour neuroinflammation on top of it you can get some nasty symptoms. It might be that we are more susceptable and or lived a life of chronic stress that lead to the brain degeneration. Unless you can really do a full lifestyle to limit stress to the max, SSRI like Lexapro might be only choice to force the relaxation and help promote neurogenesis to repair some of the damage enough to become more resilient but with long term SSRI side effects it is a tough call need a very calculated plan to transition on and off them to not get caught taking them too long and becoming worse off.
