Hello all - We just received the tandem Tslim X2 and are hoping to install tonight. I do have questions.... They've recommended we meet with someone for training. Is this realllly required? It seems like the instructions and online videos would be enough but I'm nervous to start without "official training" A big question is... How the hell do I calculate my basal rate? Currently on 40 units Lantus and around 25 units apidra a day. I would really appreciate ANY and ALL info you could share!!
