do you have a hard time getting back to where you were symptom-wise after your holiday??
It is generally accepted that drug holidays are a bad idea. Once you get on the complete protocol, (drugs and amounts taken), it can be life-threatening to stop. MAny die after going off all their meds at once. I can't think of the name for it right now.
I'd have to say though, if there are no noticeable side effects, and you like the result, then continue the practice.
We are all unique in our response to meds.
