Nancy,
I use the travel disposable type of heat pack. just peel off the back of the sticker then stick it on the inner of your shirt at the tummy area. I put every alt days during my 2ww, and I will put it there for the whole day even to bed. Will only remove it after I wake up. The brand I forgot le, but its all japanese wordings on the packaging. Just go to any travel shops like winter time and buy the heat packs can liao.
