Gift for Sister going through IVF?

My sister is starting the IVF process, getting ready to start injections and feel crappy from all the hormones. I live across the country from her, but I'd like to send a little gift just to pamper her, make her feel better during this time. I was thinking a simple box of chocolates, which everyone likes when they're feeling hormonal, but I know her doctor has her on a fertility diet, so I don't know if she would/could eat that. Any other ideas? salon gift certificate? Is there something that would be really helpful/comforting that I'm not thinking of since I haven't been through it?
