side effects

So I am dealing with two sets of side effects, now.
One is the old side effect of head-spins and queasiness in the morning. Lasts for about 10-15 minutes and is then gone. In the grand scheme of things, this is minor and totally unimportant. If I live with this for the rest of my life on occassional mornings but have no seizures, FINE! I would be THRILLED!
That side effect is likely from the Trileptal, as it seems to have been in the past.
The other side effect is the weight gain. I'm over 210 now, whereas I was in the low 190s a couple of months ago. I know that blaming the medicine is the easy way out. I could have been and should have been exercising more and eating better, having know going in that this was a side effect.
Nonetheless, I've gained nearly 20 pounds and am SOOO frustrated. I am seeing the Dr. in about 2 weeks and perhaps something can be done. Having controled the seizures relatively well, however, I don't think he will (nor will I in the end) want to change the dosages and go fiddling around just so I can lose weight more easily.
Time for better exercise routines (including going to the gym MORE OFTEN) and perhaps eating better and eating less - what a concept. But damn it that last part is just so hard to do... My diet didn't change the entire time I gained these ~20 pounds, which makes me want to blame the medication more and more, and having something to blame makes it all so much easier to deal with...
*sigh*
