ironically posting in here as I've not placed a bet on anything since September. It was ruining me financially as I was barely winning anything and totally lost any fun and enjoyment I had in betting. I was spending about £80 per month and winning a minimal amount out of it.
Having said that, and will use this as a reference point, I put a bet on SkyBet in June as one of their specials - every Newcastle league game to have at least one goal in it. Only a couple of quid on it at 25/1. So far so good!
