I was only zombie-like for the first night. To be honest, I as was glad something was finally able to knock me out. I've been on it for 3 weeks now taking 7.5mg but increasing to 15mg (full pill) tonight because it's not having the same effect. Does anyone else have any experience with this stuff? If it stops working then I don't want to keep taking a pharmaceutical if it's no longer working. My plan is to continue taking 15mg over the weekend and re-assess on Monday when I see my GP. I'm only taking this medication for insomnia and maybe some anxiety. I'm also curious to know if anyone has come off this stuff and if three weeks is enough to cause withdrawal.
