Just be a bit careful with quinine @primek and @kmakm as is now acknowledged can cause some problems.Maybe research it up a bit . A family member ended up with anaemia because of it.
One of my sons is a gym junkie who overdid protein powder trying to bulk up which caused major painful cramps.Our GP prescribed magnesium tablets which quickly corrected the imbalance. Maybe worth a try and if persists time for the doctor.But please check for any contraindications on the Herbs app.
