I've had all day nausea since week 4 and I'm almost 12 weeks. This combo (recommended by doc & pharmacist) hasn't helped completely, but helped A LOT. I missed a dose the other night (ran out & it was during snow/below 0° temps) and got incredibly sick. Has anyone weaned off this successfully during 2nd trimester? If So, how did you so it? I only take 1/2 25mg tab of unisom & my prenatal (containing 100% daily dose of b6) before bed, but nothing else.
