I too did MXE on the tail-end of MDMA one time, NOT recommended, although i was fine, but i was extremely careful with dosing(low) and timing.
with higher quality MXE, I'm left with a spiritual / well-being feeling(similar to mdma's good thoughts). If i have average MXE, I'm left with a feeling of wanting more MXE :S
I still believe the later to be MXE and it's good, just not like the pre-ban era.
I've hardly abused mxe and keep my tolerance very low still.
I've noticed after-effects from my small MXE use. although very mild, i get this feeling in the front of my head, like just above my eyebrows. Very hard to explain, but it's like; feeling I'm just starring or squinting with my eyebrows at something like when the sunlight shines in your eyes. . Also can relate to the speech thing. finding or getting the correct the word(s) to use can be hard.
Keep in mind this is very mild, and i would rather have these side-effects than the 'come-down' feeling you get from most other party drugs. mxe has nothing close to a come-down feeling.
and a few days after mxe use, i usually feel very tired at points during the day/night.. all this lasts about 5ish days.
[edit] on a side-note; mxe has unpredictable effects. like how alcohol is sometimes unpredictable .
generally i'll only use mxe when other people are drunk, or w/e.. social setting. I might try mxe in a different setting, like getting a haircut and see how that goes ahaha, I'd assume it would be similar to drinking alcohol, so not too good.
