It is a start to include anecdotal evidence.
Definition of Anecdotal: (of an account) not necessarily true or reliable, because based on personal accounts rather than facts or research.
There are many factors that can cause a plateau, most of us have gone through 1 or 2, if not more, feels is not considered evidence. You need a Jano test or at minimum another testing lab to be sure.
Although most folks can appreciate you are not feeling what you think you should be feeling, perhaps there is more to this than the peps and instead of accusing your medicine you might analyze other possible contributing factors.
This may help you find a solution.
It is unlikely that "Feels" is going to help you gather a posse.
Good Luck on your research!
