Keep some coca cola or soda of your choice on hand in the fridge for those occasions, it will work very fast to make you feel better. Then try to put a little food in your stomach to settle things out, something with bread or sugar as previously mentioned. The sugar is what really helps you recover from the nicotine spins. You over did it but you will learn your limits with experience. There's no shame in it, even experienced smokers smoke to excess and get the spins. It's no different than having too much alcohol and getting dizzy, not a fun feeling at all. It's not always just about the nicotine content of the tobacco, there are other factors at play. If you were smoking on an empty stomach or hadn't eaten much it's easy for the nicotine to overwhelm you. The same way you feel more buzz from a beer on an empty stomach vs a full meal. You just need to remember that with smoking pipe, or cigar for that matter, there is a fairly long delay from when you smoke it to when you feel it. This is due to the uptake mechanism through the mucous membrane which takes a bit of time to transfer the nicotine over through your bloodstream to where you can feel its effect. If you were to inhale the pipe through your lungs like a cigarette, you would feel the buzz immediately, because the lung pathway is nearly instant. The delay in uptake can make it hard to gauge when you have had enough. As you get experience you will recognize the effects of nicotine sooner and set the pipe down in time. Nicotine can be subtle at first in small doses through a pipe but it can build up as you found out. For me, I notice increased focus, mental speed, a boost of extra energy, not unlike the feeling after a cup of coffee. Listen to your body, and if you start to get that slightly jittery feeling like you've had too much coffee, set the pipe down and take a break. If the feeling continues or gets worse, look for a bit of soda or sugar to settle your stomach.
