Hello and welcome to Healthcare Magic. Thanks for your query.
Naltima (Naltrexone), Acamprol (Acamprosate) and Champix (Varenicline
) are all anti-craving agents i.e. they reduce the 'craving' or urge to take the drug. It is common to have loss of appetite and a sensation of general ill-feeling after quitting marijuana - and this is likely to be due to the withdrawal effects.
Usually, withdrawal symptoms
take about a week to 10 days to subside. In the meantime, I would suggest that he keeps himself adequately hydrated, takes proper rest and keeps eating small quantities at frequent intervals.
Regarding his psychiatric diagnosis, schizophrenia
and bipolar disorder
are two entirely different conditions and cannot be diagnosed together. So, please discuss about his problem and further treatment options with a psychiatrist
Wish you all the best.
