Hi Miranda,
I have been taking 200mg Raspberry Keytones morning before breakfast and lunch for a long while now (probably just under 3 months), they appear to help but to be honest it is a marginal gain I have seen compared to the exercise and diet management can achieve. Myfitnesspal is probably the easiest tool to use out there, and make sure you weigh everything initially to portion sizes right. I had no idea when I first started. Anyhow once the weight starts coming off then it tends not to stop as long as you keep with a calorie deficit and keep active.
If you're looking for a good tasty program I would highly recommend the Montignac method which is based on real french cuisine which can be really tasty. I wouldn't recommend the rapid weight loss method unless you're really really dedicated.
However to ask about the interactions I haven't seen any I think the keytones are safe with certainly PM, PC and Spearmint.
Another really simple thing is if you feel like eating, drink a glass of water.
Good luck
Arielle
