i have a three year old pit bull he had 3 seizes last year around this time and no more all year and than in the last 3 months he had 2 vet said everything was normal
Most of the time when dogs develop epilepsy, it's idiopathic, meaning there is no known underlying cause. The seizures themselves are not as harmful as they look. Your observation that it takes some time to recover is a normal reaction. Seizures take a whole lot of energy out of the body.
The good news is that this is a readily treatable condition. You will need to take your dog back to the vet since he is having frequent episodes. Phenobarbitol is usually the first line of defence in preventing seizures. You may need to play around with the dose a bit to find one that either stops the seizures altogether or keeps them to a minimum.
I know how frightening it is to witness a seizure - either in a human or a dog, but all you can do is wait it out and make sure he doesn't hurt himself by thrashing into other objects until it's over. Get him going on the phenobarb and take it from there. He has every prospect of living a perfectly normal life on medication. Yes, he may have the odd seizure here or there, but epilepsy is not a death sentence. You are lucky in one way and that is knowing what triggers a fit: nausea, eating grass, and vomiting. My vet had a dog once who had seizures every time the doorbell rang. Solution: disconnect the doorbell. Get the meds going and see how he does, but don't put him in the grave. He's not ready for that by a loooooong shot! :-)
