I looked up your other posts. You have a lesion near/on your pineal gland - which I have to guess is effecting sleep?
Have you had any lab testing?
I personally am not fond of the docs putting you on some rather strong meds when the problem is most likely caused by the tumor location, so they should work at removal... although I do hope you are on the *cocktail* for a temporary time. Please talk to a doctor or pharmacist about the side effects and how to mitigate or reduce them, perhaps changing over to another medication.
I do hope that soon you find a competent (aka excellent and most skilled, experienced) surgeon to remove your lesion and it resolves most if not all of your symptoms.
If it is a new change, I suggest seeing the doctor or an eye doctor and explaining the change, when it happened, and if something can be done about it such as changing medications etc.
it could be either. what meds are you taking and is this a side effect they list?
