Hello Dear Peg, I understand your concerns. Effexor can cause distressing withdrawals. Feeling hot when actually body is cold, nausea are most probably the withdrawal effects. Other symptoms are dizziness, mood swings, disturbed sleep and agitation. Ideally the drug should be withdrawn gradually. But since you could not afford the drug, you had to stop it abruptly. If you can afford prozac (prescription drug), it can reduce the intensity of withdrawals. At home, you must drink lots of water. Practice relaxation exercises. Usually the withdrawals last for 1 week but may last longer in some cases. Please discuss these issues with your doctor. Thanks.
