Susan, sorry you are having such a time right now. We understand that you want Mini better now. We have all been in that place. It does take time, it's not an overnight fix. Once blood sugar starts to get better so does the neuropathy. The methylcobalamin will also take some time to show improvement. I use Zobaline, Smokey wasn't as bad as the video but he did fall over twice when trying to stand. I started giving it twice a day and saw small improvement in a few weeks. I now give once a day. He is strong, blood sugar so much better but still not regulated, long term diabetic, currently has pancreatitis, did I mention he turns 18 this month.
If you and your husband can manage and willing, it is so worth what you are going through right at this time. And yes you will get angry, pissed off, tired and want to give up. Then you have a day where Mini is curled up next to you purring away, an easy day of walking, and blood sugar better even if it's just for a day, shows interest in a toy and for now it will be rare but you will be so excited. You know you will keep doing what it takes.
