I did 24/7 for 7 years (only I could do it (was application specific)) - it finished a year or so ago and whilst I miss the money (the £3 hour seems about right) - I do not miss the stress one bit. It really can get to you over time - getting woken at 1-2am and still having to do your normal day sucks. Logged on Christmas day != Fun.
If you can do it in shorter bursts it's fine but my m8 does it for his firm now (his is a flat hourly fee then if they get a call its like 30-50 an hour) and he said it's a bind especially with family (if your out and have to shoot home/office) etc.
If I was doing it now I would want a heck of a lot more money - I do minor cover now for shorter hours.
