Hey all ... again

I'll catch you all up on my progress so far. Since being perscribed
anti-depressants for anxiety attacks I've had no trouble keeping to a
healthy lifestyle. I've lost 11lbs as of this morning (I'm a little
concerned because friday it was a 1.5 less, but oh well).

I posted earlier about whether or not I should be eating more (and had
decided that since I wasn't hungry I should just listen to my body) but as
I settle into this lifestyle I find that my calorie levels are actually
dropping a bit. Here's my problem. I don't seem to be getting enough
calories through out the day and end up with a grumbly tummy at 9pm. Most
days it's between 1200 and 1300, with an occassional 1100. To make up the
difference I usually have a snack at around 9pm (when I feel hungry) and
it's usually a slice of toast (yesterday I added some grapes). I don't like
doing that for a few reasons. One is that I think it gives me strange
twilight zone dreams and the other is because I'm not comfortable consuming
calories so late at night. I'd like to stop any eating by 7pm.(Dinner is
usually between 5 and 6pm). I could start eating a snack during the day but
I find that I don't really need one (ie, I'm not hungry for one) or I can
keep my calorie levels low but then where do I go when I need to change.
Also I'm worried about my body holding on to calories because I'm not
getting enough. Or I can keep eating late night snacks (and FYI, my usual
bedtime is between 10 and 11pm) which I don't really want to do.

Now this is where y'all come in. Do I force myself to eat more during the
day (the reason for such low calories is because I eat mostly fruits and
veggies). Do I eat higher calorie foods during the day? Do I keep snacking
at night (which I really don't think is good). Do I just stay where I'm at
and ignore the grumbles of my tummy at 9pm? Soon I'll be adding more
exercise to my day (daily 1hr walks starting today) so the extra calories
will be even more important. Is there any other option I'm not considering?
Please help! I've never had this problem before.
