Sorry to hear you’ve been ill so long. Feeling unwell for a prolonged time is unbearable especially when you have no idea why because this means so much uncertainty and can consume your thoughts. You say you gave up diary, wheat, sugar, processed food and fruit 4 weeks ago which seems like a bad idea to me. It could be quite a shock to your system. If you think a dietary intolerance might be making you feel unwell why not eliminate one thing at a time for a few months just to see if you feel healthier. What one person can tolerate another can not but cutting out every item that anyone has ever had an intolerance too seems silly and could cause you more unnecessary stress with meal, planning, limiting enjoyable social eating situations and removing the chance of a nice treat now and again (slice of cake after a ride for example). It just seems to me like another chance to stress out and set yourself up for failure if you don’t end up sticking to your new diet.
Nothing wrong with choosing, healthy balanced diet to boost yourself though.
I find that eating a lot of organic vegetables from my veg box makes me very bloated and gassy and that toast for breakfast is the only thing that doesn’t make me want to have a nap after breakie but I doubt this information will spark a sudden fad of vegetable free, toast based diet plans! ;-)
For me the only cure for the brain fog, tired achy spells I get is sunshine and exercise combined but that’s been hard to come by of late. Good luck and best wishes.
