My ketostix was dark purple this morning. At lunch I had half a lager 
(but I needed it!!). When I got home an hour later I retested my ketosis assuming it would have totally disapeared and it was still purple!? (albiet slightly lighter shade).
Would it show it ketostix this quick if I'd over done it?? Have I been let off lightly?? r will it be back to pink tomorow morning?
