Stick at it, I will have given up for 8 years come December. Hardest thing I ever did but so worth it. The best thing ever is taking a deep breath on a frosty morning and it not hurting.I've given up smoking... it's going really well apart from the actual giving up bit.
I went there last month, I agree it is expensive, we loved every second of it though. Not brave enough to try cycling in the city as I think I would have died quite quickly, but we are going back!!Back from Amsterdam, blimey it's an expensive place.
