Well, that was helpful advice, wasn't it? Go home and don't worry. Now, why didn't you think of that yourself? Sheesh, you've got to wonder what planet these people have been living on--or whether they are somewhere on the spectrum where they just don't have any empathy (probably)
Six weeks seems like a long time, but don't be surprised if that all goes out the window. It's remarkable how often the goal posts move around; specialists may be good at what they do, but as a few others can confirm, they sometimes get involved with ,and speculate about, what their colleagues will want to do--and get it wrong. It can take a few weeks for all the ducks to get lined up but the time will fly. OK, it doesn't fly that fast at 2 am when you are awake stressing, but you get my drift.
Regarding the supplements--meh, if you aren't in terrible knick they won't help, they won't turn you into Superwoman in a couple of weeks if you are already running to seed and they can be a really bad idea if you get it wrong. Fresh air, exercise and sensible eating make better sense. And wine. Now is not the time to give up wine. Good luck, Marg xx
