My son 31 years was treated for depression,(his memory was not quick,hot tempered,does not like to responsibilities,had a big appetite,)Till recently he took One 200mg quetiapine film coated tablet in the night,this he has taken for nearly 1year. Recently the Psychatric stopped this drug and advised to take valparin chrono 300mg for 5 days and therafter 6oomg daily in the night. Is this ok,
