Hi! Welcome to BL, and to Blogs.
Since you're new here, you may not know that this isn't really the place to ask questions about drugs. This little corner of the site is all about journalling, miscellaneous expression (mostly word-ish, but not necessarily) and general social stuff that doesn't fit anywhere else. There are several forums, part of the
larger site as a whole, which would serve your query better. Like
Basic Drug Discussion for example. Just be sure to use the search engine and actually read what has been posted prior to asking a question, as it is very likely that someone has asked a similar one in the past.
Oh, and you might want to clarify your question, as I'm not really sure what you're asking. If I had to guess, I'd say that you're getting mild flashbacks, or shivers. Perfectly normal, IME; they will happen less often as you use less and as the MDMA loses its magic.
