Well, I use the dual bolus for all meals except breakfast (that if there are no churros: d), but it is true that it took time to use it, many times we "accommodate" or simply "try" and if we do not get the desired results toThe first, we give up ... and that is not ... you have to insist, until the goal is achieved ... I think that "almost everything" can be achieved:-/ ...
For the rest, I am glad that my advice serves you ... I also feel grateful to learn, yes, that every day something is learned ...
