I haven't been diagnosed yet. I am 47.
However my symptoms are/were :
Lack of sleep (waking up an hour after getting to bed, then trouble getting to sleep again), lurid dreams (which you remember because you wake up during them), deteriorating handwriting (signature all over the place), slowness of typing, orthostatic hypertension (dizziness when standing), starting to lose my sense of smell, constipation , declining voice ( terrible at singing and quieter) grumpy face and the beginnings of a tremor. Some stiffness when getting out of the car.
Mannitol (you absolutely must at least try this - yes it will make you runny, hold it in to exercise the vagus nerve. You can get it on the internet - it is not expensive), Exercise, Coconut oil, Low carb, high fat diet where possible. ( Imagine your brain has now become a diesel engine. Carbs is petrol. It can't cope with carbs).
Avoid milk especially skimmed and semi-skimmed (reduces uric acid levels). Cheese I think is OK.
Avoid sugar , biscuits, chocolate.
Exercise is absolutely key- Stationary bike. Gym when I have time. Need to do 50 minutes cardio + 40 minutes non-intense activity pretty much every day.
Social activities also help. Beer helps raise your uric acid levels. But not too much beer - alcohol can lower your magnesium levels which result is poor sugar control
Watch some comedy before bed. Read an historical novel which details how shit life was back in the 19th Century/ World War 1/India/France etc. Thank your lucky stars you were not born then. Or Syrian now.
Also take Vitamin b1 with coq10 - from wilkos, curcumin with pepper.
Vitamin D + K ( comes with calcium for some reason). Or go out into the sunlight at Midday and eat Brassicas
Take Magnesium Citrate as well.
Took Melatonin sometimes but not sure this helps that much or at all, so have stopped.
Current situation. Tremor gone, though may get some in the middle of the night if I have had a bad day previously (no excercise and hitting sugary snacks). Voice better. Face better. Sleep ok, but will still have vivid lurid dreams where I wake up after. Hypotension comes back with lack of exercise at work. Basically it is better if I don't eat any carbs before lunch. Smell restored.
Most of this I think be ascribed to Mannitol - is about £36 for 2 kg from Blackburn distributions. Many on Healthunlocked are also showing good results from this.
