asking to combine w/ wellbutrin

i've been on sertraline for 2 months now (1 month 25mg, 1 month 50mg) for high depression/anxiety. i have a follow up with my doctor today and i'm wondering if it's too early to suggest combining with wellbutrin? the fatigue has somewhat leveled out for me but i still lack motivation and have stopped doing so many things without even noticing. i already felt that way before, and also cope with binge eating. if anyone has any experience with the 'welloft' combo + when you started i'd love to hear your experience :)
