6 weeks is no time at all. Yes it is in your system. So maybe break the smaller amount down even smaller again. Just to be safe. You should be fine. Not on it that long at all. What some people do feel is rebound anxiety. Bit like your mind telling you that you are no longer taking this medication. So it is all in the head really. Try go a bit longer without as well. Feel nothing at all, you will know you are safe. Longer term users have to taper off them. I was on them for ten years. So I couldn't just quit them. Six weeks is a short time.
