This is totally normal, you are most likely still in your honeymoon, when your insulin needs change dramatically. Expect this to continue for at least another few months. I'm 2.5 years in and still honeymooning! Your pancreas is still trying to produce a bit of insulin on its own, so sometimes you will go low for no reason, and other times your usual doses won't be enough. Over time your insulin needs will slowly increase as your pancreas loses its ability to make insulin. However, the honeymoon isn't all bad - having your own insulin production means that your body can help out if your blood sugar gets very high, that it will take more to put you in DKA, and that you are more likely to be able to recover from a bad hypo on your own (if your body can make a bit of insulin, it is more likely to be able to get your blood sugar back up on its own by producing glucagon. However, you should still treat hypos with sugary food and drink - this is just a backup and doctors don't know how long your body will be able to do this.)
