I've been taking 8mg a day using the suboxone films. Yesterday I cut the film in half and took half in the morning and half at night. The biggest thing I was worried about was not sleeping. So far I've been sleeping pretty good (knock on wood). My anxiety is a little high but I also have major depression and anxiety so its not abnormal.
Today my mood seems to be better and I'm feeling much more optimistic. I agree with many other posters here that the less you can take the better. My doctor started me on 16mg the first day and that was way too much. On 8mg I'm feeling good and I can still feel a little of the aches in my body but I don't mind that.
Hope this helps others know what the first few days on subs can be like.
