Amoxicillin and insomnia

I'm a 29-year-old male, and currently taking Amoxicillin for a bladder infection. This is the 4th day taking it (500mg / twice daily). So far, the side effects I've noticed are insomnia, nightmares (when I do fall asleep), gas, and have recently developed this very weak, achey sensation in the front of my shoulders. You when you've been walking or standing so long that your legs ache the next day and they feel worn out? That's the type of weak, achey feeling I can compare the sensation to. And it gets worse when if lay on my sides, so it becomes even more difficult to fall asleep on top of the insomnia. Good news is my bladder infection has seemed to vanish after only the second day of taking Amoxicillin, so I'm thankful for that, as the bladder infection was very painful and discomforting worse than these nagging side effects from Amoxicillin.

The first time I was given Amoxil was when I was 17 and nothing else would stop me from throwing up. Within a matter of hours after taking ONE tablet I stopped throwing up but became extremely agitated, had trouble breathing, couldn't sit still and this seemed to worsen as it became night time as I'd be lucky to get 2 hrs sleep across 3 nights. I'm now 23 and I fell ill again recently and was again prescribed amoxil-thinking it may not happen again i took it and once again was had insomnia for at least 3-4 days and felt very unstable. At night i will shake for hours. The worst side effect for me by far is the mental state that i go through. My doctor didn't seem to understand how only taking one tablet of amoxil could affect me so severely for such a period of time. After searching for side effects im relieved to know I'm not the only one.

Taking a ten day course of 3 pills of 500MG per day. I had insomnia the first couple of nights. Some stomach problems and diarrhea. It is now the fourth day and I've been incredibly depressed and experiencing feelings of apathy and lethargy all day. Mood swings throughout the week; uncharacteristic short temper; general feelings of unhappiness or uneasiness.

Also, severe headache that lasted for the second and third days - hurt so much it woke me up several times throughout the night.

Constipation! Insomnia, (it's now 4 AM) low back ache.

After taking amoxicillin I noticed that i always had nasusea no matter what time of the day it was or when i took the pill. Out of the blew I would just feel like throwing up.
