I am a 28 year old male and being treated for schizophrenia since may 2012. Initially started on tablets resperidone for a year thereafter switched over to invega sustena. I had to quit my job before I started medication. My positive symptoms disappeared around three months after starting treatment and the negative symptoms almost completely gone recently when I joined a job for six months staying away from home in a foreign land. I feel quite confident and well. During the past period I continued to drink moderately (around 120ml, two to three times a week), and smoke around 5-8 cigarettes a day. When can I stop taking medication?
