Hello chocy963 & welcome.

Any good multivitamin should be fine. I use GNC, some people like TwinLabs but there are so many. Even Dr. Atkins has his own supplements to start Induction - try a health food store for those.

No you don't have to drink Metamucil. You will get enough fibre just from eating the daily salads and veggies on the Induction List. If at first, that is not enough, you can take a capsule of psyllium husk & that should fix either diarrhea or constipation. Lots of water helps, also Vitamin C.

You could even clear out the high carb stuff from your house before you leave. Have a good holiday and come back ready to start.
