You are right, I need to not expect instant results. I have about 10-11 lbs to lose now and it will probably take quite a while to get it off due to not having a great deal to lose.
I had similar amount of weight to lose and it took me a couple of years to get there. I also had to make a lot of changes to my diet and exercise a lot more. So have patience and keep tweaking your lifestyle until you get where you want to be. It's not easy, but it can be done.
I will try again but feeling a bit down about whether it is actually going to work.
Don't let slow progress and small setbacks to kill your motivation. Keep going until you make it. If oil doesn't work, try nose-clipping, crazy spicing and no spicing. I've done all, except crazy spicing and I found that no spicing works best for me. Especially no salt.
