Good to hear you are feeling better and welcome to the forums.

I take a prescription stimulant at a fairly high dose and had no adverse effects while using Lipomorph. Of course I recommend starting with one cap with your meal for assessment. this stuff works systematically so I don't think talking pre workout matters. Taking while fasted you may notice more minty/menthol burps and maybe some warmth in gut as a result of the capsaicin.
