Oh heck, just get a kids sippy cup!

Seriously though, I have a cup that has a lid and straw. It's plastic too. But with my tremors I have less spillage and if I drop it, it won't break and water (which is mostly all I drink) won't go all over the place.

I think we all go through times like that. DBF will go through a week dropping things. I tend to drop more right before my "time." But, as Debbie mention, getting lids off is another story. Some days I can do it and some days I just can't get a lid off of something.
