urinary tract infection
"I started taking sulfamethoxazole on my third day of having a UTI for the second time in my life and the first two days I was taking cranberry pills and drinking tons of cranberry juice and water, so by the time I started the antibiotics I was almost already healed. The first day I took sulfamethoxazole I felt my heart racing all day and at night it continued and I couldn't sleep until 4. Same thing went on for the next few days except it got worse and I would just lay in bed with my heart racing until 6 in the morning. I stopped taking the antibiotics after 4 days because my UTI went away but my heart wouldn't stop racing and I ended up suffering from insomnia for about 2 weeks. It is because of this antibiotic bc I've never had this issue"
