I have good control over my gag reflexes. Is it advisable to try taking just SN ? I'm planning to make 2 glasses just in case I puke the first one.
It's not advisable, but it is still very viable.
Taking other drugs with the SN can potentate it, as well as make the ctb process more peaceful.
Without supplementary drugs , the process will likely be less peaceful, and you'll have a higher chance of failure. But you don't NEED them. They are supplementary.
