Hello and welcome to Psych Central! Sorry we were slow getting to you, but evidently none of us knows the answers to your questions. I suggest you talk to your prescriber (doc) and maybe even a pharmacist to see if these matters could be caused by the meds.
Procrastination could be caused by a lot of things. Yes, even depression.
Best wishes. Let us know how things go.

Congrats on being in grad school!
