I think the antihistamine effect of the seroquel has been sheltering me from the dairy allergy, which i know i have. i was able to eat dairy as much i wanted without worrying. But now that ive stopped taking seroquel for the past 2 nights, the itching is back. Couldnt sleep last night it got so worse i had to take an antihistamine. I think i just have to stop consuming dairy and i'll be okay. Has anyone else noticed/experience something similar?
