Yes. This is similar to what I am experiencing. I can’t often put words to it. But it’s almost as if no 2 days (close together) are alike. I honestly thought (think?) I metabolize it differently every single day. I’m really struggling with this. I can’t take it eith food or even too close to food, it will be as if I never took it that day. Hormones, IBS/gut issues, & things I feel like I can’t even name are affecting how I metabolize it. Just know you aren’t alone. I had not thought of it being an issue with the actual medication itself. I really do think mine boils down to my body metabolizing it in such a varied fashion. I literally never know what to expect on any given day (as I’m currently laying here feeling crappy).
