I Have An Ulcer And Would Like To Take My

I have an ulcer and would like to take my medication in the correct order, I also have a new prescription for an infection of a finger nail too which is the "doxycycline hyclate" For the ulcer I am taking omeprazole 40 mg time release capsules, Sucralfate, and now have been prescribed doxycycline hyclate 100 mg. I also take Lipitor 40mg with lunch. Can I take omeprazole first on an empty stomach, then wait two hours and then take doxycycline hyclate the after taking the doxycycline hyclate wait two hours and take sucralfate?
