I think you will be fine taking the dose 10-12 hours late to start it as a morning med but it is best to ask your pdoc that. You may notice some withdrawals/side effects over night but should go back to normal one you take the morning dose. I have forgotten to take my anti-d before and after about 6 hours my body reminds me I missed it as I feel weird. Once I take it again I go back to normal. Good luck
