look you asked for advice... you should take some of it. buy a bp monitor so you can test it when you are not at work. no excuses just go out and buy one or basically this whole thread is pointless.
next how much water are you drinking? are you drinking it throughout the day? What is your diet like? Do you do cardio?
please be honest about what is going on. this thread can end up helping a lot of others down the road.
