Do not combine high stimulant doses with other stimulants
Do not use stimulants if you suffer from diabetes, cardiovascular disease, epilepsy or psychological afflictions. Also, do not use stimulants if you are pregnant, or in combination with medications (especially MAO inhibitors and asthma medication).
Make sure you don’t get too warm while using stimulants: rest every now and then, don’t wear (too) warm clothes or headgear and drink water/soft drinks occasionally.
Get enough rest before using stimulants. If you are very tired or suffer from insomnia, do not use stimulants!
Moderate use is key. Keep track of how much you take.
Drink enough to keep yourself hydrated, but no more than 2 glasses of water per hour. Exceeding this increases the risk of water intoxication.
Stimulants can give you a dry mouth, which, combined with teeth grinding, increases the risk of damage to your teeth. It is important to stimulate your saliva production. You can do this by chewing sugar-free gum. Saliva substitutes or artificial saliva (such as Saliva Orthana, Xialine and Oral Balance) can also be used and can be purchased without a prescription.
