"my doctor gave me a mix of 2 meds so i don&#039;t have the expense of contrave. i am happy with the results. taking welbrutrin sr 150 mg and 4 mg natrexone twice a day. which is the same as or very similar to the contrave. i have had no side effects. i feel a slight kick in when i first take it in the morning, which give a slight feeling of well being. i do not have increased energy and i can eat ok. i do not get cravings for fast food like i did before. i find eating healthy easier.  before i started i  loved drinking beer and admit it contributed to my weight. i do not have a problem with passing on the beer now. i am not shaky or loosing my hair. been on for 1 month only. i have lost 10 lbs. and started out weighing 219. i am 5&#039; tall and 42. no exercise."
