"Use a plastic cup to drink from at body temp. because it has a much stronger taste as it cools."
Been drinking my urine daily for about 15 years also. I would never ever use a plastic cup to pee in or use before drinking. The urine will leech the impurities out of the plastic. In fact, I avoid all plastic cups like the plague - which they are.
I have no problem at all with body temperature urine. I use a coffee cup that is dishwasher safe and from the tap to mouth as soon as it's out. Never had a problem with it. Once you've ingested it for a few days it almost tasteless and is like a warm tea - but is really pee. Standing for 15 minutes or more and it turns to ammonia and I would never drink that.
A very good read on urine therapy is "Your Own Perfect Medicine" by Martha Christy. If I remember right she drank no more than a tablespoon of her own urine per day and had spectacular results. (This book is way overpriced so you might look and see if your local library has it.)

What I found for myself is that I originally started with a teaspoon a day and over a period of a couple of weeks worked up to a cup or more per day. I discovered that the longer I used UT the less "strong" tasting that it became. In fact there are times it is very mild and actually has a pleasant taste to it.
One of the causes of the strong taste is that you are more than likely dehydrated so other than your urine drink plenty of liquids with water being the best for getting rid of the taste you don't like. Another thing that affects the taste is the type of foods you are eating. If you eating sweets or drinking alcohol, quit those for a few days and that will reduce the strong taste. In fact, I can tell by the taste of my urine if I'm eating properly.
