I Was Given Omeprazole To Treat Some Possible Pre-ulcer Conditions.

I was given Omeprazole to treat some possible pre-ulcer conditions. I also was given Meloxicam as an anti-inflammatory for a strained tendon in my knee. I was instructed to take the Omeprazole 1/2 hour before my first meal and the Meloxicam with that same meal 1/2 hour later. When I did this am - it made me EXTREMELY TIRED, light-headed and feeling generally lousy with absolutely No ambition! Are these normal reactions??
