Wondering if it's too soon

I've been taking Cipralex 10 mg for a week now, more precisely 8 days (9 if we count the first test day at 5 mg). My doctor said that since I'm not suffering from any major side effects (I'm just waking up a bit earlier in the morning, and sometimes feeling kinda foggy or perceiving my heartbeat) we can already increase the dose to 15 mg. I'm supposed to take 15 tomorrow already. Though I'm wondering if it's a good idea, because I've been reading other people's experiences online and they all seem to wait at least 3 to 4 weeks before increasing the dose.

For anyone that went through it, do you think it's safe to rush like this? Or am I risking a sudden increase in side effects by taking the extra 5 mg so early compared to most?
