I thought it may be from one of my drugs or supplements. I changed the time of all drugs and supplements and it made no difference.

I thought it was yeast, but it happens even when I eat a very anti-yeast lunch. Today, my lunch was plain steak and plain steamed spinach. Yesterday it was plain roast chicken and plain steamed spinach. Still got lightheaded.

The only thing that helps is diet soda, which I am trying to cut completely out of my diet.

As for coinfections, I've tested equivocal for babs, so we are treating it conservatively. I've been positive for salmonella, but that seems to be under control. There was also some positive mycoplasma, and the usual viruses (Epstein Barr, Herpes) but with no viral symptoms ever.

My meds are:
Synthroid, Ketek, Plaquenil, Acyclovir, ad Flexeril. I've been on Flexeril for many months, and I know that's not causing it.

My supplements are:
Artemesinin, Primal Defense, other probiotics, multi-vitamin, calcium, magnesium and zinc.

Thanks for any guidance you can give!

it could be one of your medicines reaching their "peak concentration".

You would have to check all your meds and find out how long it takes them to reach peak concentration.

I find that eating something helps to perk me up a bit.

I really think it is just that our bodies are so taxed by the disease and the meds that our up times are short lived. Stress and lack of quality sleep cause me to have the down times. I love my work but I do stress about whether I will make it through a whole day.

I found that over the holidays I took a few days off, got some much needed rest, was a little pampered and ate well. I did not get my usual pattern of ups and downs. I actually felt like a normal person for a few days. Once I returned to work the pattern started again. If I remember to keep food in my stomach things seem to be a bit better.

I think your "useless" feeling is pretty common. Your body is being hit from all sides with work, meds, illnes. It is only natural that it will try to shut down from time to time. Fighting that feeling may make you feel dizzy & nauseas. It does for me.

I really don't think it's meds. It's a newer thing, and I've played around with changing times of most of my meds.

You might want to ask about a fasting insulin test, to see if you are producing too much insulin, therefore causing hypoglycemia.

Also, if you do have the glucose challenge test, they can check insulin levels at the same time, to find out how hard your body is working to maintain blood sugar.

Last, there is a glycosolated hemoglobin test, that gives you an average blood sugar over the last three months, which can add to the picture.

When I am in that state, only certain foods help, so you might experiment. But if no food helps, then it is likely not a blood sugar problem.
