Hi there. My dr. prescribed me Tenuate (I need to lose 25-30 lbs). I was really nervous to take them because i have never taken a diet pill and I do not like the jittery feeling, not to mention a racing heartrate. Today I took my first pill, 25mg, and I feel no side effects at all. I took the pill 2 hours ago. Would I have felt the racing heart by now? Anyone with anything to tell me about Tenuate? I would love to hear about it. Will this really supress my appetite? I am sopposed to take 2 pills a day and he gave me a 2 week supply. I am a 31 year old female. I get heart palpatations also so I was really nervous about starting these things. Thanks
