"God like euphoria", lol, honestly I don't think that's a state reliably induced by any drug, really, some are more reliably euphoric than others obviously but IMHO and IM(pretty extensive)Experience, even the most euphoric ones aren't inducing "godlike" states of euphoric bliss every single time, and especially so if you're planning to do them daily. Really these truly celestial euphoric states (again, just IMHO and IME) are not truly predictable but might sometimes occur unexpectedly on deep combo sessions, and to get the truly godlike aspect you really need to be mixing in a psychedelic or possibly a dissociative at the very least on top of your basic common-or-garden dumb hedonic euphoriant... none of this is sustainable 2 days back to back in the vast majority of cases.
So having clarified that I'll choose to answer a slightly broader question which is just what reasonably euphoric drug can you do before bed semi-regularly for a bit, well personally I'd say zolpidem is something you could maybe try, emphasis on try since it won't work for everyone if you're prone to doing slightly loopy shit at a certain level of "out of it", also it's very amnesia-inducing so you won't necessarily be able to remember all that much of the actual fun experience... once the dose gets heavy enough it's also gonna be pretty cognitively disabling so it's debatable how much you can even appreciate the blissed out zonked state of GABAergic stupidity while you're on it but, personally I have fond (if hazy) memories of taking 20-30mg of zolpidem and blissing out watching some TV shows that I will have absolutely nothing but the vaguest memory of the next day... and after a short time you will almost certainly just fall asleep so there's that.
