Did you take the full dosage of 120-150mg/kg? Did you skip doses? Did you consume it with fatty foods?

That's because you took 20mg for 6 months, you didn't complete the full treatment and consume the total required dosage of 120-150mg/kg. You consumed around 3600mg, which would have been woefully insufficient. It's the people that don't intake the required cumulative dose, skip doses, and don't consume with food (fatty foods more specifically) that are more likely to experience these problems.
