The book I used was _Teach Yourself French_, by Adams, revised by N. S. Wilson. (Note that this is not a new TY book. Those are completely different and for modern languages generally can only be recommended for their recordings, if that.) It worked for me; although it is isn't really complete, it gave enough of the rudiments to get me reading. I supplemented it w/ chapters from _Read, Write, Speak French_, by Mendor Brunetti, which looks even better.
Assimil is good, but it is different.
(hape, weren't you the tiger? That pic was awesome; I've been meaning to tell you that for months. The new one is good too.)
Imyirteshem, Concentrating on the French for awhile should do the trick. And it's worth it.
