Questions about Oil Pulling combined with Urine Therapy!

I have been practising Urine Therapy for about 4 months now and have had excellent results so far. I am however trying to practice oil pulling simultaneously. Any answers to my questions below wil be greatly appreciated:

1.) Do you drink the first morning urine midstream and then wait a while and then proceed with op (as op has to be done on an empty stomach OR do you do OP first and then drink urine?

2.) If you do OP first and then UT in the morning, how do you hold your pee for so long? (coz we cannot store the pee as it has to be fresh.... and I do not want to miss out on the first morning urine benefits)

3.) Which is the best oil to use (in terms of benefits and NOT taste... as I can handle strong taste and smell!)

Thank you Kindly and look forward to hearing from you :)
