I've asked this question myself. I'm not sure there are any really quick fixes. There is no replacement for learning good coping strategies to help you manage stress better.
I like what Happier said though
Certainly in the early days of my recovery I felt that if I got through a work day without breaking down or snapping at someone and came out of the other side sober then that was a success.
In the short term all I could do was say the serenity prayer over and over, count to 10, drink tons of chamomile tea...
On day 5 I think you should cut yourself some slack and be proud of what you have achieved so far
Well done!
