I'm fine now (except the part where I'm almost 39 weeks pregnant and exhausted!)
I just ate a strict low GI diet, cut out sugars and ate regularly. It took a good few years of doing that to really calm everything enough to be able to enjoy treats without falling asleep after eating them, but it didn't take long to improve the overall symptoms after sticking to the low GI diet. Little things like eating a handful of nuts if I had a treat, regular snacking, making a list of low GI things I could eat so I could keep them on hand and graze throughout the day. Baked beans on burgen bread toast became a staple in my diet!
Hope you feel better quickly and get some rest and take care of yourself too!!
