I think it's winter! I been having higher readings since cold weather hit.... my summer readings would be around 5-6 in the morning and no higher then 8 after food and now it's 6-7 in the morning sometimes higher and below 10 after food! And I haven't change anything food wise or exercise wise.Don't know what's going on, past few days getting 9's before bed mornings 8's and high 7's. Like you been drinking wAter and walking to try bring it down. Sleep is getting worse also. 7.2 this morning And 8. Yesterday morning have good day everyone
