Yes, although they (methylphenidate) seem to slowly become less and less effective, but maybe it is just me becoming used the medicated state. They are enabling me to "sort" important and "discard" unimportant memories much more effectively, as not to say at all, prior.

Edit: The grestest benefit of the medication was the ability to concentrate properly and me being able to do tasks that I had pushed away from me before. It essentially enabled me to get my shit together.
