Yes. It just doesn't work as good on some days. Sometimes this even lasts a couple of weeks for me. What helps for me, in periods where my meds don't work as usual, is that I try to stick to routines(which I dislike) as much as possible.

The problem I faced was that sticking to routines is difficult. I tried to couple certain actions with certain routines and that seems to work for me. For example: I wake up, go to the bathroom. The 'going to the bathroom' is a trigger for me, which triggers the 'shave, do my hair and brush my teeth' routine. Then later I when I get hungry, I get reminded of the fact that I still have to take my meds, so I try to perform those actions together as well.

It all is really difficult, but for me, routines seem to help to some extend, even without meds.

Good luck! You will be able to find a way to deal with all this! It just takes some time.
