Hi Frankie
If you take more artificial sweeteners in coffee or tea, you will face some side effects such as Aspartame has been linked with many symptoms like headache, change in mood, memory loss and various cancers. symptoms associated with sucralose are gastrointestinal problems (bloating, gas, diarrhea, nausea), skin irritations, cough, palpitations, anxiety, moods swings, depression, and itchy eyes.
So better to reduce the intake of artificial sweeteners in a day. Use only 2 tablets in a day or 1-2 packs in a day.
