Maybe you need to introduce something more solid than brown cows and yogurt.....something more solid to settle your stomach?
Good point on the potential changes in insurance coverage. The copays and % coverage of trt can change during annual renewals. Many businesses review their health insurance policies on a calendar or fiscal year basis and the changes can really add up for those using these expensive drugs. With increases in the cost of insurance coverage is sometimes watered down, resulting in small increases in premiums, but poorer coverage.
Sounds like your digestive system isn't used to the extra fat in the diet. Of course, the meds don't help either. Yogurt does help my stomach, but try to find something other than no-fat or low-fat if taken with meds. Hope the tummy settles down. Best of luck.
