Summary
A person with long COVID tried something that gave energy but brought on post-exertional malaise once they used the energy. They took one 500 mg metformin pill and had a hell of a rollercoaster for 2.5 days: severe nausea with throwing up, tiredness, cold sensation, rapid breathing and weakness. A later post said a 500 mg pill gave nausea, fatigue and weakness, and they felt horrible for four days. They warned others with long COVID to be careful with this medicine.
