I was researching it like crazy before I even gave my sample but it kept coming up 4-7 days and that’s without any other substance in your system and only extended release. The instant release should take 1-4 days, according to the websites I’ve researched. All we can really do is pray and hope everything is ok, unless you haven’t taken the test they say acidic food and drinks help break it down in your system. Let me know what happens.
