Hi,
Three times in one night is kind of a lot to handle a snake - he may have just been expressing his desire to be left alone.
As for the eyecap you can try the tips in the "bad shed - no poblem" sticky but it really isn't a big deal and it would be betetr to post a picture to get peoples opinions on whether or not it is a stuck eyecap first.
The last thing you want to do is remove an eyecap that isn't there as it can blind the snake.
