Taking propranolol/sedatives to combat clen sides - counter-productive?

[FoxOscar]

I have a poor tolerance of clen. I take propranolol occasionally for anxiety and tried some while on my last clen cycle. It did help calm me down, slow my heart rate, feel less hot etc but my question is does that diminish the effect of clen? If you don't feel these side-effects does that mean clen is still working?
