Damn man, the amounts you use are insane. I think the 3.5 grams of MDMA every other day is your big problem. That is going to cause a TREMENDOUS level of tolerance to all serotonergic substances (which includes psychedelics and, yes, methylone). In addition it's going to absolutely wreck your brain chemistry, if it hasn't already. I strongly recommend not doing that and giving the MDMA a big break. Eventually you'll find you'll be able to trip on semi-regular dosages of psychedelics, though likely your tolerance will be permanently jacked up over most peoples' (mine is, from doing way too many psychedelics though, not MDMA).
You referred to 5-MeO-DALT, 5-MeO-DiPT, and 5-MeO-MiPT in your post, not sure if you really meant those or if you had typos, but either way, those dosages are tremendous. If you really took .3 grams of 5-MeO-DiPT in a dab, you could seriously hurt or kill yourself using that, it's killed people at lower dosages than that.
