the 150mg of bupropion sl made me hyper but i took it in the morning and it was pretty well worn off after lunch and i had no problem sleeping at night but now he wants me to take the full dose of 300mg. i will take 150mg twice a day !! once in the morning and then again 8 hour later!! will the last dose of 150mg keep me up at night? i do take ativan 1mg 3 times a day as needed!!
