Yes you can take the acidophillus without the detox. The windy, tired, no libibo has nothing to do with your age, its the effects of feeling ill and although I'm not a doctor, I am an expert patient.
I saw a nutritionalist at the Royal London Homeopathic hospital. I wrote a 3 day diary of what I had eaten and when, this was helpful. At this point I, like you was aware that I had an adversion to wheat.
I dabbled with this, in a confused way, making sure I ate lots of yogurt. It wasn't exactly a chore but it did take up time and thought, constantly watching what I ate. I would feel good sometimes but then it would come back again, for almost no reason.
I am busy, with 2 boys and I don't like being under par and not able to be myself.
So after years of experimenting and researching I found that this did the trick. It is extreme, I did feel great and looked good.
Summer is a good time to do this. Salads and grilled chicken and fish are light meals that all the family can enjoy.
I discovered the delights of the all the different variates of rice that are available including rice noodles for stir fries. I stopped sugar and substituted honey. I found Redbush tea, which isn't tea but is refreshingly like tea.
So yes you can take acidophillus without adjusting your diet and it will/might help. However I would think if your gut has fungus in it, this fungus has to be starved so that it will die and to give it what it likes, to feed it will keep it alive. Maybe only just surviving but one special meal could trigger the onset of another attack. The beauty of this diet is that it is gluten free. By following the diet you know that you are not feeding the fungus anything that it likes and that way you will have cleared your body of toxins and can then start afresh in the knowledge that you are clean inside and then you will be able to eat anything you like. I love my food and not to be able to eat what I like and when I like upsets me.
This method is quicker than being constantly aware of what you can and can't eat.
It took me sometime to find products that I could eat.
The Village Bakery Rye bread is yummy and is 100 per cent rye.
Corn pasta is OK much better that rice pasta, which turns to glue in less than 5 minutes.
Corn tortillas are great with humous and advocado. Goats cheeses are excellent.
Soya Milk with vanilla was good with rice cereal with honey for breakfast.
take care
