We have discussed this one at length.
Weeks or months ago now.
I think it was fair to say, that the consensus was that further in-depth research revealed some side effects associated with that medication such as insomnia, which is obviously counter-intuitive to the condition being treated.
IHL-42x's safety and efficacy were considered superior, but you might best DYOR on that because of our bias here.
I think Jeol did make some reference to it, in the last few days, some other posters may recall that comment better than me.
From memory I think that medication treats the condition not the cause where 42x treat the cause... I think!!
I think if you use the advanced search function on Hot Copper with that medication name and IHL you will find that discussion.
Good luck
