Return to Lantus

I decided to return him to lantus today just fill like overall he responds to it better I could be just totally wrong but switched him back anyway we shall see how he does. Its been 7 days now and he is doing well other then he has been drinking more last 2 days not sure whats up with that I will check for keytones soon just to make sure all is ok with the urine. His appetite was down 2 days ago but its better today.
