For the past couple weeks I have been in consultation with my doctor regarding some alarming symptoms, including severe tiredness, more asthma attacks than usual ("usual" is none at all...) and a constantly upset stomach. Several possible diagnoses were presented, some more severe than others.
The final diagnosis is a fairly trivial matter though: I have developed an allergy to milk. Since I drank a lot of milk and ate a lot of yogurt and cheese, I was constantly having an allergic reaction. Hence the tiredness and stomach problems. The asthma attacks were also being triggered by the reaction to milk.
It seems that cheese and yogurt do not bother me as much as plain milk, but I am cutting back on all consumption of milk products. And I have been feeling so much better! Today I have more energy than I have had in many weeks, and have been cleaning and doing laundry and sewing and cutting fabric without feeling like I am going to die any second :)
I have also been delving deep into my sewing room and gathering items to sell at my quilt guild's annual "garage sale" tomorrow night. Anything quilt related is welcome for sale, and I have rounded up quite a lot of fabric and kits that I know I won't use. I sincerely hope that people in my guild will want them- the money would be a nice addition to my vacation fund!
