So we moved offices today and as a result I’ve not been able to access Revit or Dynamo all day.
Same tomorrow and I’m on leave next week.
Is there some sort of support group for my withdrawl? 
Please send help!
Bah, this got flagged as spam… Surely not every post has to be serious?
Be careful, Dynamo can become a dangerous addiction.
I advise you to turn to the Dynamoites Anonymous to stay sober from this software.
Not that I encourage feeding an addiction, but you can in fact execute Dynamo through Revit Viewer Mode (which does not require a workstation key).
While you can’t make any permanent changes in the Revit environment, you can change and test your graphs.
I can’t go 8 hours at this point…
