@hamsterman thanks! I'm in the same boat and recognize what you say (the randomness etc). It's only been a week since I "discovered" ME/CFS. Until last week, the physical degradation which I had been suffering from for more than 20 years was just a big mystery. I realize a lot of people on here are experts at ME/CFS and still haven't been able to achieve remission, which should really make me more pessimistic. Instead, I haven't been this excited and happy in years. That will probably subside in time, but it's been a blast discovering all you people who are finally pulling the curtains off of my illness. Not to mention discovering all kinds of symptomatic treatments which where hitherto unbeknown to me.
But yeah, as far as timeline, I've quit all social life almost 2 years ago, I've stopped leaving the house about 9 months ago (except for grocery shopping once every 2 weeks). So I've been extremely carefully pacing to combat randomness.
