yes, but its not reccomended....any lethargy/withdrawal will appear a couple days after stopping and generally last for 1-3 days (most of which is due to caffiene withdrawal).
if you want to cycle stims with thermorexin to maintain strong effects with the other stim (thermorexin has little down regulation in "energy" effects- though there is some tolerance-)
some stims like ephedrine, clen and amphetamine derivatives can tax the adrenals and CNS with extended use.
Thermorexin works very differently and causes little receptor downregulation or depletion/strain on CNS/adrenals.
