You use clinical deodorant but halfway through school it stops working HELP?

It sounds like your clinical deodorant might not be providing the all-day protection you need. Consider reapplying it in the morning and possibly keeping a travel-sized version in your bag for mid-day touch-ups. Additionally, ensure you're applying it to clean, dry skin and consider using a more potent formula or trying a different brand if the problem persists. Staying hydrated and wearing breathable fabrics can also help manage sweat throughout the day.
