Phil......the smell and bad taste is probably keytones (acetone foul pear drop taste) . You do need to drink water regularly otherwise yr urine will be foul and yellow due to yr bg being so high and will be at some degree of risk to developing kidney problems.
I think you should get yrself to hospital A&E and just say that you cant get yr bg to lower with the amount of insulin you are using. Probably insulin by iv will work and yr bg should lower. You can then see a D specialist and let them stabilise you. Dont eat ice lollies that contain sugar.....make them yrself with fizzy diet lemonade or sparkling mineral water.
Agree with iHs. Your health and bg's are too high and urine analysis etc would substantiate this.
You need to get to hospital via a&e although wouldn't recommend a weekend todo it.
You should not be smelling anything!! It isn't insulin...
