Last time I was on it I started at 15mg and worked up to 30mg over two weeks. 15mg is typical starting dose for acute mania. If mania is not present and either depression is or no mood episode is than starting dose is usually 2mg-5mg like you are on. Maybe try ro wait it out a bit but if you see no imporvement shortly maybe it is not for you. I know my pdoc kept telling me I would build tolerance to the sedation but I tried many AP's very unsuccesfully in that department. I also had insomnia as I was pretty manic, but still felt very sedated, you are right it is a pretty strange feeling.

It's always a good idea to write it down and track your mood, sleep, anxiety etc daily when having a med change so that you can see how it is really effecting you, sometimes easier to see on paper.

The very first time I was given an AP I was told to take it as soon as I got home. So I did, I managed to sit in a chair and stare at the wall for four hours, because I could not move my body or think. I had to be at the school to pick up my kids..yikes!! Some of us are more sensitive to the sedating qualities of these meds.
