Nearly 2 weeks, I kept doing it for a couple if weeks here and there then if ruin it and give up so hoping I don't do that this time , feels like I've been doing it forever as I'm always stopping and starting and when I'm not doing it I'm planning on doing it, I lost 4 stone on lipotrim last year (but put some back on )so I know it works and because lipotrim went up to £38 a week I just couldn't afford it then found shake that weight for a lot less and it tastes nicer which is a bonus
