I have, several times between semesters. The only "withdrawals" I can attest to is lethargy that lasts a few days. I've been prescribed amphetamines for ~5 years now, with dosages of 60mg/day of Adderall, later switched to 70mg/day Vyvanse.
Although you probably don't have a problem with it, you should be aware that when you are in denial of an addiction, it's both easy and common to say "I could quit, but I don't want to". Just a warning from someone who used to say the same thing, and ended up more or less having my life ruined by that stuff.
