If you are hallucinating I would go the ER, that is not a good sign and your chance to have a seizure isn't good (I'm not trying to scare you but something to think about)... I never hallucinated but I shook like crazy, I went to the ER and they had put me in detox for 3 days, gave me meds to help with the shakes and precaution meds so I wouldn't have a seizure. I never had one.
If you can't or don't want to try and get a friend to stay with you so at least you are not alone. I'm sure you must be sweating a lot? I did ALOT... but that is a good thing really.
