I know this has probably been discussed a million times but I am doing 5IU ED and having trouble getting all the 5IUs injected during the day because of work and eating carbs around proposed injection (heard you can't eat carbs within a hour window??). But if I can't get 2 2.5IU shots during the day would a single 5IU shot in the morning do just as good or better than 2 2.5IU shots during the day?? Also is the carb 1 hour window true?
