I learnt this myself through years of usage.
google about "caffine opiat effect", I'm not the only one who's found this.

it doesn't matter how many people on google say so
it's arse. You're talking psychosomatic effects at most. The only reason to mix caffiene and opiates is to try and stay awake when you overcook it.

I'm not even bothered, to tell you the truth. I take them because I like them and the effect they have on me. Phsycosymantic or not.
We all do things that aren't good for us, and life is a pretty pathetic existance if you don't.

I know it's bad for me, but it does have some possitive effects, if it only had negative ones then why would I do it? The doctor explained to me both why it was bad for me _and_ why it was having the effects I've described.

I don't mean to sound bad, but if you want someone to change their attitude towards something, dismissing everything they say as 100% twoddle is not the way to go about it, you'll only get their backs up to the wall.

Google scholar says 'no'.
But if it makes you happy then guzzle away. What's the worst that can happen?

Well ... apart from it being one more link in the vicious cycle that will eventually lead to you shitting through your armpit into a bag hanging off your wheelchair.
