First time poster here. I quit my vyvanse/dexedrine combo a little over 2 months ago after being on it for 5 years (a dose of 140 mg vyvanse at one point, legally prescribed..somehow, though admittedly I would take the occasional extra, so that figure could very well be 210+mg somedays). I can't say I feel much better yet.. in fact, I feel as if my mind is stuck in a tar pit throughout most the day. I am however beginning to experience real emotions and human connection again, so that's always nice. I've experienced the usual/expected effects of quitting such as anhedonia, slowed mental processing, lowered sex drive, anxiety and fatigue, but there's something I did not expect that has ended up being the worst problem: insomnia. I cannot go to sleep at night. If I do fall asleep at night, I usually wake up at 3-4am. It's like my day and nighttime wake/sleep cycles are inverted.. I feel a lot more awake at night than I do the day time. I've pretty much exhausted all techniques on sleep hygiene, such as working out in the morning, not looking at a bright computer screen after 10, taking melatonin, keeping my room dark and cool etc. but nothing has helped.
Has anyone else experienced this when they kicked their stimulant medications to the curb? If so, how long did it take till you were on a reasonably normal sleep schedule? I'm currently in grad school and if anything were to cause a relapse, it would be this daytime fatigue from getting 3-4 hours of sleep.
