Hey twirls! It's only been three days, but I would go back on my regular dose and let it build back up in your system.
I don't think you have to start over again. You haven't been off of them that long. BUT.......DO NOT TAKE THE MISSED DOSES that you've lacked for three days. Just start up on the prescribed dose and let it take over. You will start to feel the difference by the end of the day. It is imparitive that you NOT try and make up for those lost days. I say this because that's what people sometimes do when they miss a dose.......they think they have to make up for the missed ones. AGAIN I SAY............DO NOT DO THAT!!!!
Good luck and feel better soon.
