Psychotropic drugs are double edged sword. Although they are so much effective at the same time they are harmful too with lot many side-effects and they should not be altered by a lay person. Now that your mother has manic episode, she needs to be on a proper dose of mood stabilizer
and an antipsychotic
such as olanzapine
and Lithium are supposed to be better as compared to oxetol. Relicalm and q mind are different class of anti psychotics.
Lastly regular exercise and good diet will also help.
