Hello, i was diagnosed with adhd two years ago, and was priscriped inspiral 10 mg / 20 mg SR, so far everything was working fine, but suddenly from March 2022 , that Medicine stopped working, i was confused, tried everything but it just did not worked, even switched the brands, still same issue, then one day luckily by chance i got the older batch of inspiral 10 mg ( expiry year 2022), and it worked !!! It seems like the new batches are not working anymore, they seem heavily adulterated, what can I do about this? Can you tell me which batches are still working like the old one's?
