Synthroid and Topamax

I was just diagnosed with hypothyroid today.  My doctor has started me on Synthroid.  What's more, he was shocked that I had managed to lose any weight at all with thyroid disease, and told me that I would have a much easier time controlling my weight now! 
Who would have thought?  I've lost 10 pounds completely against my body's will!

Also, he put me on Topamax to control my migraines, and told me that it had a known side effect of--guess what--weight loss. 

I'm kind of worried that the weight will come off too fast now (ironic, I know).  Anyone have any experience with either of these drugs, good or bad?  I need to be on both of them for matters unrelated to my weight, but I just was wondering what to expect the scale to do once they start kicking in.  Any advice?

I've been taking synthroid for over a year now... it was impossible for me to lose weight before taking it, but it didn't change my weight dramatically, i had to diet and exercise to lose all of the weight i had gained because of thyroid problems...

I found that synthroid didn't really make me involuntarily lose weight.  The thyroid hormone that helped me drop weight quickly was cytomel.  On synthroid I just found it a bit easier to maintain my weight, instead of keep gaining like I was pre-synthroid.  It's the cytomel that has made my metabolism take off and work the way it should have been all of those years.  Though I still have 7 pounds to lose (and I don't really HAVE to lose them as I am in the healthy weight range for my height now, but I'd like to lose them), I'm finding that I need to eat more than I ever have before, and I am still losing.  You will need to keep a close eye on your weight, and keep tabs on the number of calories you eat to determine what amount you need to lose/maintain/gain.  That's all the advice I can offer you... it's different for everybody, so perhaps the synthroid will have less/more of an effect on you than it did on me.  Who knows.  But feel free to message me if you think I can help you any more!

I started Topamax two weeks after starting calorie counting, and the biggest thing Ive seen is a reduction in my appetite. But it is unpleasant, because it's accompanied by slight nausea and dizziness. Plus one of the side effects I had heard about was that soda and some beers no longer tasted good, and when my boyfriend offered me a sip of his soda today I found out that was right! I am losing at the same rate I was before I started taking the topamax. 

Ditto here...Synthroid has been a life saver for me...giving me my life back to me. Since I've been taking it for aobut a year, the weight has not melted off. I notice that the less I eat and the more I move the more weight comes off...and when I had migraines I was eating lots of sugar, salt, and I changed my diet and they went away.
