Don't give up trickrick.
It's better to try these things out on a small scale, if its not working then walk away.
I've never been that much a fan of half time betting. Whenever I have dabbled its been on the draw though. I'm finding myself moving further away from any kind of 1X2 betting and sticking to markets with just 2 outcomes, like Asian Handicaps or U/O.
Good luck anyway.
