starlight, can you tolerate milkshakes? my friend was told she wasn't gaining enough too and started drinking a few of those a week so she could put on a little. and it is good for calcium so she drank those. id on't think i've gained any weight yet either, but i sure look like i have! all belly.
and don't be afraid of the ride. We visit my family weekly.... they're 45 minutes away. and we have to visit all our family on christmas- so 35 minutes to one home, then another 10 to the other, then 45 back. you'll be alright, just amke sure the belt isn't across your belly.
