I don't know if being bipolar you can take this,but my sister in law gets a strong diet pill called phetermine(?) and she dropped so much wait so fast.But it can be a major stimulant so I guess it might put you right into mania which seems to be the biggest concern w/ docs about such meds.I pushed my doc for adderall b/c of sleep,focus,and weight gain issues. I have been taking a low dose for alittle over a week now and it will help the weight I can already see a huge difference in the over eatting issue. and It (so far) as not made me feel the least bit manic.
