He was high this morning...I would not decrease the dose at all...he needs to stabilize and needs all the insulin he can get to obtain some semblance of consistency.
I know the lower numbers can be a bit nerve wracking...but you're doing good. Just test and keep an eye on him. Remember the walk down the dosing ladder is still in front of you - which means shooting green numbers.
Take a deep breath...you have support here.
P.S. Any chance you could add the url of your last post to your first post today? I was wondering why NS on some days previously...but I'm running out of steam and have a big day tomorrow...and just don't have the energy to go looking for them. No notes on your SS - perhaps you could refresh my memory? Was it due to the vomiting??? Thanks...apologies that I'm exhausted and don't recall the history.
