Reductil (sibutramine) is, as SG!!!!!!!! says, no longer available through official channels in the UK because the evidence suggested that it wasn't safe.
Most folk who took it when it was prescribable either didn't find it at all effective or struggled to tolerate the appetite suppression. It's fairly predictable that people who are overweight because they enjoy their food aren't going to like the reality of taking a pill that makes them go off eating, however much the idea appeals in theory.
Orlistat is the only slimming pill still available on NHS prescription. At a pinch, it might provide a marginal benefit over diet alone in some people.
If you hang out in the wrong places, you can of course get all sorts of gubbins, from Tenuate Dospan to home-brewed Aicar. But it's not worth it.
You have to choose The Evil Pixie. Unlike most of last year's crew of idlers and wastrels, at least you can be sure that she will TURN UP and FINISH. Even if she has a broken leg. You've seen her do it before, and had the picture of your homepage to prove it
When I went skiing a few years ago for the first time in 20 years, my calves hurt so much that I was in tears going up the drag-lift. A change of hire boots sorted the problem out, and I have my own boots now (I bought the identical model to the hire boots that HAD suited me) and don't get any problems.
As for running after skiing ... no, never had a problem, though I've also never felt that I've benefitted from a week skiing and doing some running at altitude.
Going skiing makes me realise why I keep doing that boring running thing. It's great to be able to ski all day without worrying about fatigue or aerobic fitness
