Hey y'all I took mucinex (just the regular kind) to help my cough be more productive I've taken it before. For some weird reason I'm kinda high from it. I didn't expect that . I feel relaxed/tingly lightheaded and kinda spaced. I'm concerned for two reasons 1) it's about time to take my temazepam so I don't want to get too messed up. 2) I just heard ur can give you weird/bad dreams. I suffer from night terrors ( that's what the temazepams for) and I certainly don't want a bad nightmare. Mostly it's just odd to be high without expecting it.any information on why this is happing? Thanks
