Doing more than 6 sessions per year

Hi,

I am doing MDMA for my cptsd and ptsd. It has been somewhat helpful in clearing my dissociation but I could not really go furter/deeper. The one time I was able to was when I combined it with shrooms. Since when I do only MDMA alone, I use dosages of around 200/225mg. With the mdma + shrooms trip, I would use smaller dosages of MDMA because both amplify each other (around 125/150mg).

Could I do more than 6 sessions, maybe 7 or even 8 sessions in a year where I use MDMA? I read somewhere that some people took mdma for therapy 7+ times and nothing happened.

any thoughts?
