Been off for 2 weeks

I did a fairly quick taper but I was down to 10 mg for awhile. Went to 5 for al couple of weeks and then 2.5 then stopped. I've definitely been very irritable and my head has felt "heavy." Only way I know how to describe it. I've heard the 2 week mark is when things start to get rougher. Anyone have any advice or what I should expect? If it gets too bad is it safe to take a small dose again? I need some encouragement because I'd really like to get off this stuff.
