Injecting urine

Hi everyone! Hope you can give me some advice.

I recently discovered Urine Therapy and got very interested in it. In the past week or so I have attempted to drink my morning pee but am finding it very difficult. I just can't seem to get used to the taste and feeling of it in my mouth and it's a huge ordeal even drinking a few drops of it. :(

I already rub it on my skin, but I was wondering if it's possible (and safe) to inject it.

I'm insulin dependent diabetic, so I'm injecting myself is a normal every day thing. Would it be OK to inject the urine?

many thanks in advance
