Started 9 days ago. 150 once a day. Haven't smoked. Insomnia teh...

Hey Kat, I've been taking Wellbutrin XL 300 for about 28 days now and have just started having trouble sleeping 2 days ago and a nightmarejust a bit agot. I'm trying it for ADHD rather than depression (no results really yet, but is it just getting in my system thus the sleep issues?). Anyways I actually had missed taking it the last 2 days because I misplaced the bottle but took one yesterday and after working a rare extra job for 13 hours I was tired but didn't go to bed until 3am which isn't real out of the normal, but then I woke up a couple times and for good at 6:30am after a Nightmare. Before going to bed I was worried about no waking up in time (10am) because I was so tired and normally I am a great sleeper. I wonder if this will stop, at least the nightmares...don't think I can take dying in a car crash and spitting up blood so much that I'm going to die choking (my nightmare, yikes!). Also it might be giving me the chills, or maybe i'm getting a cold?
