Is it possible to eat 1 hour after taking the Niferex 100mg pill? In eating I mean eating something with dairy, or do I have to wait exactly 2 hours??

I just started to take the pill and I do eat 2 hours before taking the pill but then I have to wait 4 hours until I can eat again and my stomach does not like that. Is there a way I can shorten those 4 hours to less?? Also when reading on websites about taking this pill I read that it should be taken with water, but I take with juice, can that effect something during those hours?
