I don't know anything about what dosages are safer...
No offense, but asking for advice on something like this doesn't make much sense if you are going to go ahead and do it before hearing what the advice is...
Things like this can be pretty dangerous, but I don't want to scare you cause I'm no expert, it's just that I also take an SSRI and when I was interested in doing this I made sure I did research first and when I found out it wasn't safe I steered clear.
In worst case scenarios serotonin syndrome can be really bad.
My guess is you will probably be ok so don't worry, but if you start to feel really bad in anyway I would seek some kind of medical assistance...
