It could have been brought on by not taking the meds each day, maybe it was just bad days.
However it is good to get a routine going in regard to medication. Pill Boxs are a good idea. I would forget to take mine. Or sometimes I had already my medication but forgot I had taken them.
I take more than just one pill. So now my chemist gives me my pills in a pack for the week. Days are marked and the time of day to take them. Now I know for sure if I have taken them or not. It has also helped me to establish a routine.
So whatever works for you......... make sure to take your medication as advised so the dips are evened out.
Good Luck
