I was placed on xanax for anxiety/depression for 6 years and then taken of and placed on valium which has been for the last 2 years which i have now decreased to 2mg then ceased. for the past 9 days i have had contsant head pressure, head feels like a heavy weight, neck saw, migaine sypmtom, nausea, unbalanced walking, head spins, eye fuzzyness, and the feeling i have had 10 beers or smoked marajuana and it is that experience that remains its freeky. Is it normal to have head pressure constant, migraines, non stop when withdrawing from valium? how long will these remain if they are from valium?
