I understand that injecting twice a week may not improve things with everyone, but keep that in mind if it would come to that. Good points in the LowT reply. I guess in this case it all comes down to how is it that you feel just before the next injection. If it's ok no need to adjust, if it's not bearable then adjust.

By the way, what do you do if you for example would need to travel and wouldn't be physically available for the scheduled injection at the office?
