Hey guys

T - Transient amblyopia/ scotomata
L - Light sensitivity ( increased )
S - Snowy vision.

3. Gastrointestinal symptoms :

D - Diarrhoea
G - Gastric irritation ( cramps, N/V, failure to thrive, etc )

4. Cardiac symptoms :
( mnemonic - 3D's and 3S's )
D - Dyspnea
D - Decreased heart function ( hypotension, bradycardia, irregular pulse )
D - Dysrhythmia
S - Syncope
