My last grad student paycheck came right as I started the new position so it easily could have been a longer period of time between paychecks. My grad department was one that always supported me during the summer and so I haven't had this sort of drought for a long time. It might have been easier had I known it was coming (I wouldn't have spent a ton of money at Ikea the weekend before I started if I knew it was going to be so long), but I doubt it is ever easy.
In celebration, I am going to pay my utilities! And part of the credit card I've been living off of!
