Hi FleurdeLis
Welcome
It sounds like withdrawal, but whether it is or not, I always advise people to see a Dr if they feel unwell or worried in any way
This is a link to some of our member's experiences of detox and withdrawal - for many people it's simply uncomfortable, but for some of us it can get pretty hairy.

Congrats on getting to day 3 - what you typed sounds pretty normal round here - you're in the right place
Hope to see you around some more
