A relapse in itself may often be triggered by recalling unwanted events, memories, at times maybe an unconscious action, which could lead to experiencing heightened existing symptoms. The triggers may not be the same for everyone therefore each person may experience triggers to their own individuality.
Regarding your son's alcohol mix with sleeping tablets, (and possibly not being aware fully of the intake amount) may have had an adverse effect leading to his excessive behaviour changes as you had described. If this mix has had an effect on his stability of mind, medication controlling his symptoms may have been affected, that could have resulted in a partial return of Schizophrenia symptoms, triggering a possible relapse effect.
Of course you may need to check with his GP, health professional or mental health team for an accurate and confirmed clarification.
As you can respect direct advice cannot be provided as to how to proceed from here, but if you have sole responsibility for him, then to consider what actions you feel you need to take in order to help ensure his safety. Of course he may respond in a way to reject any help you may offer and may find yourself having to make difficult decisions when he denies to you all awareness of his symptoms.
Its not easy, to try help as you hope to, to decide what would be the best course of action, Medication is often the main contribution with schizophrenia to help offer some suppression, control and balance, outside of medication therapy may help with the understanding and coping methods, but as the problem lies within the mind, your son may struggle to cope alone not knowing the reality of his thoughts and behaviours.
You may have to make decisions, difficult at times, but maybe to remember that what ever actions you decide to take has been done with care for him, for the best possible outcome believed at any time, for your sons safety and welfare.
I expect the MH team would only section him after carrying out an assessment of his conditions, behaviours and state of mind.
I hope you may come to make the right decision if need too, and you son regains a level of balance soon. Consider keeping others around you supportive and not to take all the pressure alone.
Feel free to talk anytime you wish too.
