I had to stop taking all meds before surgery, and wasn't allowed to start back up for two days after.
I felt side-effects from that for sure
Luckily I was in so much pain that it helped mask the side-effects. lol
I downloaded an app to help me remember to take my meds. It tells me what meds to take and when.
Now, you just have to get up immediately after shutting off the alarm, and take the meds, or you can forget that it even went off. Maybe that's just me.
