Hi Michael,
First, it's great to see the huge progress you have made in the last months. You now have an effective pre-pack to control the symptoms of any "waking state" release, when you take it before. That's a great, great improvement !
Next step is NE management, of course. I agree, they are unpredictable, and can happen a few days after a waking state release, or before the usual delay. I have that too, but happily, it happens far less often as I age ( I am 52).
Did you try taking the exact same pre-pack you take before a planned release, as soon as you are aware that you had a NE ? If so, what were the results ? From what you have written, I guess that the B-complex part of your pre-pack version does not work very well as a "post-NE pack". In that regard, I think getting some quercetin, curcumin and flaxseed is something worth trying. I use them, and they are also useful post-NE, even if best when taken as a pre-pack. Also, they are all safe supplements, and all three are largely recognized as healthy substances.
Whenever I have "leftover POIS symptoms", be it from a NE or else, I have to take some supplements every 4 to 6 hours, to control those symptoms. I usually cycle between supplements from one supplement dose to another, for better results. This imply I use some interesting supplements that are not in my pre-pack. I stopped stacking things in my pre-pack when it got to a point of reliable efficiency. but that does not mean that supplements like vitamin C, ginkgo, Moducare, taurine, pine bark extract, berry extracts, and so on, are not helping against my POIS, and I often use them and similar ones against remaining symptoms.
I think you would be afraid of how many supplements I have here in stock...lol . Many POIS sufferers tried so many supplements, alone or in combination, that we often end with a full cupboard. I even have a box in the basement with those that I did not tolerate well, along with a note of what happened when I tried them ( we never have too much information, so I collect alI the info I can). However, I have around 30 supplements I use, that I know have positive effects for me, be it for my POIS, for sport, or other reason like when I have a cold or else. My current trend is to eat more veggies and fruits through my green smoothies, and take less supplements, but my anti-POIS pre-pack is still essential and cannot be skipped.
Claritin D 24hours is not available in Canada neither. But, it is over the counter and easy to mimic. If someone takes on regular Claritin 24hours, along with a 60mg tablets of pseudoephedrine, at the same time, and then 12 hours after, results are equivalent. There are many brands of plain, 12 hours pseudoephedrine, like Sudafed, ask the pharmacist to show one to you if interested in trying it, and make sure that the formulation has no other ingredients in the formula ( and, of course, check with the pharmacist if this is suitable and safe for you).
About fish oils and flaxseed, I must underline that I do not take the flaxseeds for their omega-3 content, but for the lignans in it, which are good antioxidants, and NMDA receptors blockers, so good against excitotoxicity and anxiety. For omega-3 , fish oils are a far more effective source, but flaxseed oil is an alternative if you are vegan. So, you will see that I have BOTH omega-3 and flaxseed oil in my pre-pack, but for different reasons
I have developed my pre-pack as a whole, so it's hard to say which is the more important - they all are. I have made many tests over many months, I have tried many pre-pack versions, and at the end, this one was satisfying. I even have considered the cost/effectiveness ratio of it, so I have eliminated more expansive supplements like Moducare, which was otherwise part a an equally effective previous version of my pre-pack ( I had already in mind the project of sharing my pre-pack composition on the forum in order to help other members, so i wanted it to be more accessible, cost-wise).
Let me know about your progress with NE symptoms management, Michael !
