One time, I missed my pills for 3 days, and I found myself hiding behind a chair after the biggest fight in the universe with my girlfriend, and there was a... suicide was a pretty big thought.
Then, this one time, I didn't take my pills at night once, and I couldn't tell if I took them or not, because my new phone doesn't say whether a pill alarm went off or not, and I found myself hiding under a desk thinking about killing myself again.
So then, this one time, I went to a new doctor, and he changed my dosage to once a day, and increased it a bunch, and I found myself 'wanting' to hide under a desk. I evened out though... and boobs happened.
So yeah, for me it sucks when I miss a dose. But eventually I'll even out, but before I even out it feels like the world is flying by and I have to make split second decisions on everything. It's pretty stressful. That said, it looks like you're post op, so I have no idea. It also looks like some around here have missed a dose or two and not had much happen. I use a pill box organizer thing now, and keep a few doses on me at all times in case I'm not home (I travel a lot).
