I've been gluten and dairy free for a few months now - what I'd do for a bucket of chocolate icecream!!
I'm not doing it for any particularly autistic reasons (I think), but because I suffered from lethargy, dizziness after eating and chronic muscle spasm pain shooting down my back. I used to be in excruciating pain, but thought it was a normal part of having a job, and would collapse afterwards. I needed a nap after a visit to the shops, or hanging out the washing. Now, I can survive a day at work without the pain, and have the energy to take the dogs for a walk afterwards. For the first time in years I can stay up to watch tv after 7pm if I feel like it. I'm hoping to be able to attend this years work christmas party without falling asleep for once!
I started this diet thing, because my mother discovered she was lactose intolerent. When she removed lactose from her diet, her arthritis was dramatically reduced. Apparently lactose intolerance is hereditary, so I thought I'd give it a go. I've always known that bread makes me feel dizzy, so I threw in the gluten for good measure. If you're going to torture yourself, you may as well do it properly!
I currently live on a diet of corn cakes, soya milk, tofu, beans, rice, fruit, vegies and lots of hot curry and meat. It's not so bad, but it means you can't buy takeaway as often as you might like. You can get gluten free breads, but they seem to be better designed for propping up buildings than eating. It makes eating with others embarrassing, and you irritate people who offer you yummy treats like cake, biscuits etc. Most people seem to think you are doing it to be difficult - but hell, who cares what other people think!
This is not to say that the gluten/lactose free diet is a miracle cure for all my woes, but it seems to have more benefits than disadvantages in my case. I still freak out and get sensory overloads in shopping centres, I still stim, I still don't like mixing with people. I still suffer from anxiety and depression. I don't think I'm any better at recognising people, or communicating with them... and yes, one session of christmas shopping will send me running home screaming...
