1. Both my doctor and pharmacist said that it was ok to take Omeprazole with other medicines, so it should be alright to take it at bedtime. Having just re-read the long speil that comes with every box of Omeprazole, I note that it does state "It is recommended that you take your capsules in the morning."

3. In the Uk the NHS does not believe in taking multi-vitamins, unless you have a spefic problem (for example taking Adcal which contains vitamin D3 due to the adverse effect of Pred on bone density).
