Summary
Crocus 75590 fell ill after a COVID infection in early 2022, with fatigue, breathlessness and brain fog, then a reactivated EBV and mononucleosis. After about 18 months they felt almost normal, but a cold brought the exhaustion back and things worsened. Still working, they take ADHD stimulants to get through one activity a day, with tachycardia and insomnia.

Their words about each treatment
- Adderall · Worse
I have ADHD and have a prescription for both Adderall and Vyvanse ... tachycardia, crash, insomnia, even more tired the next day
In context ↗ - SSRI · No change
I started an SSRI in 2021, but after I had covid it stopped working and I switched to an SNRI.
In context ↗ - SNRI · No change
I do not think being on or coming off the SNRI has affected anything in a positive or negative away.
In context ↗ - B complex · Not said
I have also been taking B complex, Vitamin D, magnesium glycinate, turmeric, and occasionally zinc.
In context ↗ - Fish Oil · Not said
I recently introduced Fish Oil and plan to start CoQ10

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 chart starts 18 months after onset: the story doesn’t say how ill they were before that. 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.
