All the reading I've been doing has me convinced that low carb is what my body needs. Since I had my baby I have gained a bunch of weight, that's right since, not during pregnancy. I gained the perfect amount of weight while PG and followed a very strict gestational diabetes diet. I actually felt like I had a metabolism for the first time while PG. I kept up mostly with the diet with a few splurges, but I've still piled on the weight and nothing that worked before is working now, like ww. I avoid sugars because I feel awful after and I exercise as much as I can fit in, but nothing is working. I'm exhausted all the time, but I usually can't sleep when I try to. I can't say my baby keeps me up either because he usually sleeps 10 hours a night. I also get bad headaches and acid reflux, and had fertility problems due to PCOS. Oh, and my memory is absolutely awful, I am beyond mommy brain, sometimes it's frightening, I'm getting scared to go back to work because I really need my brain to function there. Sorry for the novel.

I'm just hoping that this lifestyle will be the answer for me. I am also waiting to get into see my doctor to get my TSH levels checked in case that's part of it. Do you have any advice on getting started and sticking to it?
WOW, firefly - it's like you were typing my story out! Except that my diet during pregnancy wasn't as good, so I did gain during. AND after. But for the last 5 years since my baby was born, I felt pretty much exactly the same way you did. I quit all carbs on July 29th of 2011. I now eat fruit, but that's it for carbs. The first week was HELL as my body was detoxing, and it FELT like I'd been on hard drugs or something. Shakes, migraines, dizziness, nausea, etc. That feeling passed.
To date: I still maintain a carb/gluten free diet. I exercise 3 to 5 times a week (although I slacked off this past month since I was travelling for Christmas), and I've lost 80 pounds since that day. My PCOS is also under control for the first time ever WITHOUT the use of Metformin. Normal periods the last few months. My insulin, blood sugar, and other hormones are all finally NORMAL too. (I had a blood test just last week, so that good news is current.). My sleep patterns are better, I feel more rested and my extremely fuzzy brain is sharp again.
My specialist OBGYN told me last month that my body cannot handle carbs, and that it's a good thing I got off them. She told me that in the future, if we get pregnant again, to keep eating that way, because it's a very healthy diet (when you do it right).
How I got started: if it helps, I drank protein shakes (chocolate ones) to help me get 'extra' protein for the first few weeks. It also helped me work through the "chocolate cravings". I got the Costco brand "Premiere Nutrition". Each has only 1g of carbs, and 30g of protein. I don't drink them any more, but they got me through the first few weeks, while I was trying to figure out how to cook/eat a balanced diet without bread, pasta, rice, and sugar.
During those weeks, I ate unlimited salads, veggies, and made sure to have a healthy sources of protein (eggs, chicken breast, fish, etc). And 1 to 2 of those chocolate shakes at "snack times".
Anyway, they helped me at first, so if you have trouble giving up the carbs, it might help you too.
