Welcome to the Forum jrhett55!!
Withdrawals can vary amongst people, mine pretty much got better with each day, but the first week was generally quite rough, and I too was in work, the best thing is to hang in there, the initial period has to be done to get to the better times, I found loads of fresh air and fluids very important to get through work!!
However if things get very rough or anything that you're concerned about, check in with a Dr, some withdrawals can be serious, so be safe!!
