Agree with Hale,
First above all it's far too soon to say that you are not insulin dependent : please watch your levels very carefully, they may gradually start to rise but they may also rise very quickly it you develop an infection of any sort.
For interest though there are people who find that they were misdiagnosed in the first case and have another type of diabetes and it's not just a case of T1 or T2, diabetes comes in many different varieties.
MODY, (a genetic form of diabetes)
This occurs in about 1-2% of people with diabetes in the UK . It can be misdiagnosed as T1 when it develops in the young as in the case described in the link (it is genetic so normally other relatives have diabetes (often diagnosed as T2)

There are other types, sometimes they really don't have a label so get called 'atypical diabetes'
Some people of certain ethnic origins (mostly but not totally Black American and SW African as they are beginning to find similar types in other groups) have a type of diabetes where insulin dependence and hence the risk of DKA seems to come and go . This is sometimes included as a variant of type 1 (T1b) and sometimes called ketosis prone T2. (the actress Halle Berry who famously said that she had cured her T1 through diet may have this type of diabetes)
