Just randomly off my head:

• Ditch the extra probiotics, veggies (to be more precise, their fibre content) are probiotic enough;
• Getting enough sunlight = Vitamin D?
• Getting enough vitamin C? (doing whole30 you should be)
• Are you getting enough sleep?

Anyways, it would be helpful if you gave us more details about your eating & sleeping habits, the environment you're living and working in, and how you have been eating before doing the whole30...

Cheers!

You'll get better answers than this I hope, but have you been tested for allergies? Could it be an environmental allergy like mold? My husband's allergies are awful and I'd think it was the flu if he hadn't told me it's allergies. As someone without allergies, I didn't realize how bad they can be till I married him.

If you just started, then being sick twice in the first three weeks is not surprising; it's just standard low carb flu symptoms. I was sick at first too. The general story of low carb flu is that your body is undergoing a massive chemical transition, from burning carbs for fuel, to opening up fat-burning pathways instead. So don't sweat it.

Given that you've been sick for a while, you can expect that to change as time goes on. I was also a rather sickly person, but once I got over low carb flu my sickliness pretty much disappeared.

If you've been paleo for a while, then we need more info: what do you eat, how do you sleep, etc. People with severely damaged metabolisms have to start more strictly. For example, Chris Kresser talks about some patients who have to follow something very close to the GAPS protocol (I forget what that stands for, but it begins with nothing but bone broth, then includes meat, then some veggies, then more veggies, and so on).

You have to be having a reaction to something that is causing your cold-type symptoms. Do you drink alcohol? The only kind I can drink w/o aftereffects is 100% agave tequila. Do you use vinegar? Vinegar always messes with me no matter what kind. Are you being hyper-aware of your grain consumption? i.e. Soy is hidden in everything.

Sleep, sunlight and stress were the first things that came to mind when I saw this post.

Being paleo is not a cure-all unfortunately, it does help over-all health tremendously though. Even though you get sun where you live and take some supplements perhaps you are not getting enough vit D, could consider a test to see what your levels are. Sleep is a huge factor in health as is stress, the 'terrible-twosome'. You may have some under-laying chronic metabolic derangement that does not manifest itself in obvious ways. Don't be afraid to go to your doctor and request a full work-up of tests, I thought I was dam healthy a few years back until i had a few basic tests done that showed some markers that needed improving.

I used to be sick all the time too. My doctor said my thyroid was a tiny bit low. I beged him to treat me for it. He di and now I am 70% better which is good enough for now. Levthyroxine fom 35mcg to 75mcg now.
