s part of the problem -- it takes about 4-6 weeks to notice if a med is going to work or not.
Side effects, however, start immediately, because all these meds are artificial to the body. Twitching is a common side effect of antipsychotics, but not so much with antidepressants, but we're all different. It might be a problem with magnesium, as these meds interfere with the absorption of magnesium (and vice versa if taken at the same time).
