I've been in a situation like yours once. I was really upset and didn't know what to do. By that time I was reading a Derek Sivers's book Anything you Want and I was feeling so much connected with the author that I've decided to send him an e-mail telling my story and asking for some advice/guidance. For my surprise, he replied my e-mail on the next day. I think his answer fits to your question, and by the way, it was exactly what I did and it couldn't have been better.

Mr. Sivers's answer: "Quit now. If your heart's not in it, get out. Be honest with [...]. You're not helping them or your self by doing something you're not excited about. :-)"

Don't be afraid to quit.

Honestly , I think that's the best thing to do, I just didn't have the courage to do it. I have 3 months notice period, So I guess I better hand my notice in this week ..

3 months notice even though you started only a few months ago? Is that legal?

I don't know anything about UK employment laws, but at least here in Finland the notice period is capped based on length of employment (e.g. only a month if you've been less 2 years, up to 6 months for 10-year careers).
