Not low carb, no, around same as you most days, occasionally higher @ around 400g. It could have been some other factor, but I have no idea what. I noticed it by accident when I had skipped a Reta dose (indo Monday - Thursday for Reta) and noticed a had a much better pump several days after the missed dose. I lowered down to 500mcg on Mondays and Thursdays, and have since been getting better pumps consistently. It could be something else, like I said, but the correlation makes it seem plausible at least
