I had 4 veeners done on my front teeth now the teeth feel tight pressure which wakes me. Advice?

You should return to your dentist to have the teeth and veneers looked at.  At this visit the contacts between the teeth will be checked to see if some minimizing of contacts is needed, to see if excess cement is stuck between the teeth and to check the bite forces on the teeth and veneers.

Hello. Go to your dentist to check your occlusion and veneers when you chew and correct any thing is causing pressure.  

Some possibilities are the contacts between the teeth/porcelain may be very tight, which should gradually dissipate over a few days.  Or perhaps there may be some residual cement that wasn't removed entirely that could be providing the pressure.  Another possibility is there may be biting interferences or collisions that are producing the pressure. This can be easily adjusted by having your dentist check your bite with articulating paper and polishing the high points that show on the teeth/porcelain.  Also have your dentist check the health of your gums and verify there are root infections that can be identified on X-rays.  

New crowns/veneers can feel tight at first.  Shortly after their insert, the tooth socket ligament adjusts  to allow for a comfortable fit.  If your veneers feel tight for any more than a few days, their may be excess cement or the contact points between them may be be too heavy.
Followup with your doctor and explain your problem.  This should be resolved with cement removal or some filing in between the teeth.
These recommendations are based on the assumption that the final restorations have been placed.  

Go in for another consultation. New Periapical X-rays and a 3D CBCT scan might be needed. Your dentist will have to check you clinically, o make sure there is no infection, decay, or ill-fitted veneers.  There is a possibility that the pain is due to either trauma or clenching or grinding pressure as well it's important to check the bite and many other factors.
