You have 2 option here depending on which makes you feel most comfortable. When you take the next one, you can just take it at 5:00 & then keep taking it at 5:00 every day. Or, if it makes you feel more comfortable, take the 2nd one at 6:00 & then the 3rd at 5:00 then continue on taking them at 5:00. Now that I think of it, there is a 3rd option...take all of this month's pill at 7:00 & then switch over to 5:00 next month. It is safer to take them around the same time every day; however, it is not mandatory that they be taken at the exact same time every day. Part of the reason to take them at the same time is that you will be more likely to remember to take it if you're on a set routine!!!
The pill has never made me sick to my stomach; so what I'm about to say is just my personal opinion. When any meds make me sick on my stomach, I make it a point to take them right after eating a meal ; so there is something in my stomach beside the med that I'm taking. If you read the instructions, a lot of different meds say that you should NOT take them on an empty stomach. I've only ever taken a couple that suggested taking them on an empty stomach. Therefore, when in doubt, I opt to take my meds right after I eat!!!
