Hi,
Welcome to the ehealthforum and I am glad to help you. The prolonged sleeps which your mother is having is likely due to the use of sedatives or drugs which she might be using.
If sheâs dependent on drugs, then she needs to consult a psychiatrist and will likely need a counseling session by a clinical psychologist. She will need to undergo a deaddiction programme also. I sincerely hope that helps. Take care.
