Aw, get well soon, mama! Your remedies sound solid, nakita ko rin ang ganitong approach sa ibang preggy moms sa group ko, and honestly ang Vick's + tulog + lots of fluids talaga ang go-to combo natin since limited lang options when you're pregnant and diabetic pa. That dry cough can linger for weeks though, so if it doesn't improve in the next week or two, better check in with your OB just to make sure everything's okay with baby din, kababaw na check lang usually pero peace of mind talaga. Glad you're staying hydrated and taking care of yourself, yan ang pinakaimportante now. Rest well!
