Wow. I'm really sorry that you've gone through such a bad experience Trollheart.
Being so attentive to your sister, being the one who helps her through every day must be a heavy burden - one that you can't shrug off the way people do with their jobs, etc.
You need to look after your own health, and if Ensure does the trick that's excellent news. It's not like dietary supplements have a reputation for addiction or damaging side-effects - you know, like steroids, heroin or something (
* checks VU back catalogue for songs about Ensure*).
Anyway, as I hope you know, there's always a place for you on MB to talk through your probs.
Take Care, Lisna.
