First question is;

Is it okay to use Propranolol (40mg) with Sertraline (50mg) and Risperidone (0,5mg)? I use Propranolol at morning and night (For essential tremor), Sertraline every morning and Risperidone every night.

Second question is;

If it is okay to use those together then what are some things i should avoid in my daily life such as alcohol, nicotine, etc.
