Apologies @AutisticLegoLover for using the incorrect term by saying it wears off, when asking a question, but there is no need for your rant !!
I am fully aware of the half life and that it builds up in my system.
I have also read the instructions and am merely asking a question because I can't figure out the answer on the leaflet which I've typed out. Meia Culpa.
As an aside, I completed agree with what you said on the other post about people not researching the product and looking for quick fixes.
