"i have been on qsymia for about 2 weeks on the low dose 3.75. i was a little nervous about taking this after reading the reviews but so far i haven&#039;t had very many side effects. just had problems sleeping a little other than that everything was fine. i&#039;m not sure if i lost anything i haven&#039;t weighed myself yet. i start my higher dosage tomorrow and will update everyone next week."
