Sessions done every two days are not well-studied, but one subject reported
an unpleasant episode a few years ago. These are not suggested.
Sessions done every four days are likely to elicit stronger metabolic snapback
than is needed to accomplish your goal in choosing to do a series of sessions.
If you repeat sessions on any schedule, you will be doing what this software
calls 'series of sessions'. A series of sessions should consist of either trying different session designs, or
doing the same session three, four or six times in a row. It is NOT suggested that you go back and forth between
two session designs, as follows:
And so forth. This pattern of use has not been tested, and one report
of negative effects appeared after sessions done on this pattern. The instance is very unclear, as the individual
was using many mind-altering techniques at the time, and there is no way of knowing what the cause was, but in
principle, conflicting input is possible, so this is best avoided. The same applies to rotating between three session
The risk is that activity in the areas you want active will spill over
into areas you don't want to have active.
Sessions too close together can be like holding a microphone too close to a speaker. Sounds that have nothing to
do with the actual input will appear, and they won't be nice to hear.
