Yes---I needed medicine for the cbt to work it would have not made sense to me because I knew everything to be fact(even when it was a delusion) when I was psychotic. I see medicine as one tool---I was on it for 2.5 years including a slow taper off. It doesn't have to be forever----the current recommendation is like 6 months symptom free for psychosis and then you can taper off. So here is the question do you hate medicine so much that you are willing to ruin fabulous vacations etc to stay off. Untreated psychosis tends to progress and get more confusing over time and while cbt is helpful you have to have the right mental state for it to work at all. Other than medicine mindfulness meditation has been shown to be somewhat promising but I really recommend meds for short term stabilization....
