Hi, sorry to hear that your meds aren't doing the job. I also got my meridia 15 from Egypt, but they seem the same strength to me. I have had a break from them and always find they are more effective for the first couple of months. Whilst i'm not advising you to do this I usually have cola or coffee with my reds and it increases the effect. I've never tried trim right so I can't compare but I hope what ever you decide works for you. Good luck!
