1. Go for tablets over liquids, gels and creams. Pepto tablets over liquid. Pain tablets instead of pain cream.
2. Go for sachets and flat-packed tablets instead of tubes and bottles. Bottles are the ultimate space-suck.
3. Look for travel size packaging.
4. Remove items from boxes, or flat-pack boxes to save space.
5. Store items in the empty space of bottles.
