User blog comment:Semedre/How to get 2 Fevers/@comment-73.189.2.183-20150719225031

ok so dumb question but how do you know when the fever gauge is filled enough to be activated by the next lesson? No matter what I do I can only get it to activate by my 4th or 5th lesson -___- whenever I try to fill it more i accidentally activate it and when I count the amount of days it takes to activate it and go to the next lesson it never works?
