Apologies if this is in the wrong forum.
This may seem a bit odd but i've found that when i'm taking a generic, one-a-day multivitamin, I feel really tired a few hours later and then all day.
After a quick sniff around, it seems some other people find that taking a multivitamin does the same to them. It never occured to me that something that should be making you more energetic was having the reverse effect.
Anyone else encountered this? Is it really the multivitamin or something else at work (or not at work as the case may be)?
