Day 21 of Humaworm

I am on my 21st day of Humaworm and I have been SO TIRED! I feel like stopping it because I feel so down. Does this get better? Should I taper down? I am ready to feel good and not so sleepy and depressed. I do not like feeling like this... sleepy, depressed, annoyed and hermit-like. Does this feeling go away shortly after the 30 days is complete?
