Where did you find this ? It seems incomplete, and has some grammatical errors. It isn't really a sentence, since it doesn't have a subject and verb. It's just a collection of clauses and phrases.
I would expect something more explaining what happened after the month of procrastination.
Such as "After a month of doing other other things, he finally decided to work on his thesis." The boldfaced part, showing the contrast between before and after, is missing in your example. Note the boldfaced section contains the actual subject and verb.
