Methylpred DP and pain medicine

I am taking methylprednisolone on the 6 day course, am on day two. I am also taking Panlor pain medicine. The combination of these two has produced a very interesting and for me a very pleasing side effect. When I am layed down to sleep, but not quite asleep, I get a somewhat mild euphoria. Then followed by hypnogogic pre-dreamstate imagery that is sexual in nature. Then when actually asleep and dreaming the dreams have been incredibly vivid and intense, in one case a nightmare that resulted in my physically yelling and waking up, which is highly uncommon for me. For me nightmares or intense dreams are a good thing, I am a sometimes lucid dreamer and I enjoy such experiences. I am hoping that these side effects continue. Other than that I get a mildly upset stomach because I do not follow the directions and drink a full glass of water. I should note that this side effect is not present on the Panlor alone, only in combination with the corticosteroid. I was given the steroid to reduce inflamation of my sciatic nerve, and so far it does not seem to have helped, but its only day 2. I might also add that I have been happier, more likely to laugh, although I am not typically depressed or anything, I assume this is a more latent form of the euphoria some people experience.
