Extacee, I would caution you against anything that is making you feel like that.
You are doing so well on the plan you have in place, are you sure you want to do anything differently? You are seriously not playing when it comes to your weight loss and I know this couldn't have been easy for you. It seems you have the motivation to continue to do very well. Your pace has been steady and solid afterall. Surely by swimsuit season, you will be rocking it.
By the way, I did Alli for a while. It helped and my side effects were minimal. I never felt anything outside my digestive tract.
