"standing at 5&#039;3&quot; i weighed in at 228lbs monday sept 14th, started phentermine tuesday mornin sept 15th, within 20 minutes i felt a rush come over me, my heart was racing, i was sweating, numbing feeling in my arms, as well as, i felt that i couldn&#039;t get the right words out, almost tongue tied. then about 6-8 hours later at dinner, i kept feeling like i was moving in slow motion. side effects, the verge of a headache, not one, but could be triggered at any moment, dry mouth, and insomnia. i can usually only get 4-5 hours sleep tops. which is extremely difficult with a 2 year old. but i have already lost 3lbs, i am keeping to a 1500 cal diet. no exercising yet due to heart rate being elevated at simple movements! will start next week! i&#039;ll keep posting"
