I am testing MX235 for a couple weeks, one spray to each wrist, one spray to the chest, one spray to the neck.
I did not notice anything different happening, since everybody always reported such good experiences with MX135, I expected a lot form MX235, bur I got a kind disappointed. I also became a little cranky everytime I tried it MX235.
If MX235 is like MX135, then I wonder if MX235 has the same or some of the contents from MX134, since MX134 makes me very cranky and impatient.
I am absolutely over the moon for mx235! 
Maybe you could try using it in different locations? Like maybe 2 to the neck and 2 to the chest…really get it close to your face and nose for awhile and see if anything changes? Or maybe you need to use more sprays so it hits you with a higher concentration? I will say that I don’t notice any self effects from it until about a good 15 or 20 minutes after I have sprayed it. I’m sure someone more experienced can offer more help…but don’t give up just yet!
