Any one with any tips on supporting her or experience of the side effets of medication- nausea etc ?
I'd be inclined to wait to see if she does actually experience side effects. Every medication we take has a long list of potential side effects: not everybody experiences everything, some people don't feel any.
If she does suffer from mild side effects, I'd stay calm and practical in the first place, like you would about any other medication.
My dd who is a student has been on ADs for quite a long time: her problems are fairly serious and she would not be able to function without them. But with their help she is able to live independently and keep on top of her studies. To me, it's no different to the blood pressure medication I take: it is something I need to function and keep me safe, there are some side effects, but there is nothing disturbing in the thought of the medication as such.
If you are in the UK, presumably it will be another month and a bit before she goes off to uni so that will give her a bit of time to acclimatise.
I would advise her very strongly to contact her Personal Academic Tutor (or whatever the equivalent is at her uni) as soon as she gets there and explain the situation. This shouldn't be something she needs to be embarrassed about: academics are very used to these conversations. Her tutor will know what support is available. It won't count against her in any way, but will be useful to have her situation registered if she needs support later on.
