My general doc said to me last year (or longer), you should consider adding a daily multi-vitamin, it can't hurt. I did ask if it wouldn't hurt, would it help because I HATE pills of any sort. Always have and always will - even pre-band. She said that she thought I could get benefit from it and whatever I didn't need my body would flush out. (Doc translation to normal person speak: You're getting old. Take a multi-vitamin. *sigh*)
I did think about it various times. Thought about chewables, but when I asked about the yummy kid kind she said she preferred me taking an adult one intended for woman. Grrrrrr. She said there are multiple liquid ones out there. Uh, have you tried those? They make me want to barf. And yes, I am a whiner, but reality is if I can't stand it or it's going to make me feel like I'm going to barf, I'm going to take it all of 3-5 times max.
And while some people may be deterred by the 50 cals per daily pack, not me. I have faithfully eaten my pack every day and it even gives me a candy fix as an added bonus, which works for me somehow. I might not be the best barometer for these in regard to the band since I don't have much if any fluid in my band (.2 whenever the heck I was last in), but I have zero problems with them.
