Having taken unisom for period of time...and then stopped using it. My withdrawals were horrible. Nausea...so bad I missed 5 days of work. Of course, I was taking more than recommended. If you are on this website asking about unisom...I am the only one telling the truth. If you are hooked...you will need to taper off this drug like any opiate. I know the label says this drug is not addictive...again the medical community showing a complete misunderstanding when it comes to addicts, drug and addiction. The label says take only as many as allowed per day. Ok Mommy, says the addict. I'll only take one. I know there are people who have probably over a period of time increased their dosage and really aren't addicts. Will they suffer withdrawals. YES
