Summary
A Reddit user who described about four years of symptoms and said they were in the "vax injury camp" (the Pfizer shot if relevant). Two weeks on cetirizine hydrochloride, an H1 antihistamine, improved their symptoms dramatically, which they estimated as an 80% or more recovery. Writing about a year later, they said they consistently feel better when they catch a cold or the flu.

Their path
How ill they were on the ME/CFS severity scale, estimated from what they describe at each point, with time counted from when the illness began. Hover or tap a point. The first step with a time is 4 years after onset: the story doesn’t say how ill they were before that. The dashed part: the story doesn’t say when. 1 step says too little to place on the scale and is only in the table. Dates are when they posted. What the levels mean.
