I don’t take those drugs
Either, sorry.
I joined WW and boy I love it! A VERY supportive community there on Connect, their online version of community
I’ve lost 34 pounds and it helps with the fog which could be food sensitivities. (As it turned out in my case)
They’ve got a good thing going there
I’m online only with WW. ❤️

I used to have only 1 cup of coffee every morning but I've stopped drinking coffee all together and only have it on rare occasions when I've had a particularly poor night of sleep. The longer you drink it for the more you need to keep up the caffeine rush as your body gets used to it and therefore you feel more tired if you don't drink more. I found that the sleeping problems I have has improved since I stopped consuming coffee on a regular basis. I used to have spells where every few months I'd go weeks with only 1-4 hours of sleep per night... But now it's become a more seldom thing and when it happens it only lasts 1-3 nights instead of weeks. The "fogginess" is also happening on a rarer occasion as well.

If you have a juicing machine at home maybe try to make a fresh green juice in the morning. The nutrients are absorbed straight into your bloodstream and therefore gives an instant boost if that's you need to get going in the morning. The juice needs to be consumed straight away as it looses it's nutritional value and goes super bitter if you let it sit, but you could clean and cut the ingredients the evening before and store them in a box in the fridge ready for the morning. The combo I use the most is:
1/2 cucumber
3-4 stalks of celery
1 peeled lemon
1 sweet apple
About a thumb sized piece of ginger, peeled and divided into two or 3 and stuffed inside the cucumber and lemon to get more juice out of it. Sometimes I add a handful of spinach or kale just to get a bit more alkalining ingredients in there. I read somewhere once that the combination of cucumber and celery juice makes a potent detox for joints, so that's a bonus for you if you have joint problems as well... I used to have it really bad on a daily basis and then I did a week of juicing and found that it made a difference to my joints. It wasn't until after I had done the juicing cleanse that I read about the cucumber/celery combo. Most of the recipies I used had them both already in them. So I did another week of juicing a few months later and now I my joint only bother me in really hot or cold weather.

I take a B-Complex vitamin supplement at lunch to help me with my energy and fog. If you don't mind my input, the Keto diet is a fad diet that nearly all medical researchets agree is very unhealthy. A person may lose some weight in the short term, but gain it all back later. A person needs low-glycemic carbohydrates for energy as well as lean protein. Add a small amount of healthy fats then you have a recipe for energy , weight loss, and health. Sleeping well helps too.

I found that switching to gluten-free did help a bit with the energy levels, I didn't use to have a problem with gluten untill after my fibromyalgia symptoms kick in properly.

When I've had a week of very low energy I usually "reboot" on a Sunday by doing a 24 hour cleanse. It's got a strict time schedule for when to drink water with freshly made fruit & veg juices and teas, it's all you have all throughout the day. It hard to not have solid foods and you do feel drained towards the end of the day when the toxins built up in your body start to release, but it's just for the one day and you are still getting nutrition from the fruit and veg you drink, but its do worth it as the next day I wake up feeling like someone has pressed my reset button as I'm full of energy and I go off to work with a spring in my step.

Sorry, I’m allergic to those two drugs. My reading isn’t too positive on them. Keep a pen and pad by your bed and write everything down. My hubby said to me years ago when I couldn’t find the right word, “if it doesn’t make any difference to your story, go with what comes to mind”. I do that a lot. I also close my eyes to listen to anything important. It blocks out the other things going on. Good luck and welcome.
