I've been taking inositol for over two years for OCD. I take a dose that should be clinically insignificant, but it seems to have helped a lot (admittedly I am highly suggestible and cannot deny the placebo effect). In high school I was "treated" with SSRIs and felt like a zombie. Things went away on their own later in high school and throughout college, but I started inositol during grad school when mental symptoms increased again. I've been searching around for long-term effects but haven't found anything. If you come across any information pertaining to long-term effects, please share your knowledge. :-)
