For some going into ketosis is fast and others a little bit slower... I do not use ketostix at all - I did not have any of the symptoms described for ketosis (bad breaths, grumpy, tired, headaches...) but as long as you are losing weight, drink all of the daily recommended water.. this is a good sign
The first couple of days, I had a bad headache and it was due to the body flushing out all the caffeine, sugar... but I drank a little bit of water with some salt and also bought some electrolytes tablets (NUUN) to help out
Good luck to you and welcome to the forum !
Have a great IP day !!
